In this work, non-equilibrium molecular dynamics (NEMD) simulations were employed to investigate the effect of hydrogenation modification of single-layer graphene on the interfacial thermal conductance (ITC) of gallium nitride/silicon carbide heterostructure. The findings demonstrate that the ITC of heterostructures exhibits a non-monotonic trend, initially increasing and then decreasing, with increasing hydrogenation concentration. The calculation of critical parameters such as phonon density of states, phonon participation ratio and phonon transmission function reveals that this phenomenon originates from the competition among multiple phonon transport mechanisms, including enhanced interfacial coupling on the SiC side, inelastic phonon scattering and phonon coherence. Subsequent research has demonstrated that the spatial distribution of hydrogenation configurations significantly influences ITC. At equivalent hydrogen coverage, the random hydrogenation mode results in an ITC increase of up to 34.2 % over the ordered mode. This effect is primarily attributed to the random distribution, which enhances phonon coupling between hydrogenated graphene and adjacent materials while mitigating detrimental interfacial interference. Additionally, the effect of ambient temperature on ITC has been systematically examined and quantified. This study elucidates the dominant mechanisms of phonons across different frequency bands in thermal transport at heterointerfaces and provides a theoretical basis for optimizing thermal interface materials via controllable hydrogenation.</div></div>","PeriodicalId":336,"journal":{"name":"International Journal of Heat and Mass Transfer","volume":"261 ","pages":"Article 128519"},"PeriodicalIF":5.8,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146161472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study expands a previous work on the stagnation zone heat transfer to cover the entire wall-flow up to the hydraulic jump, for a wide variety of arriving profiles, subject to the influences of liquid properties, gravity, surface tension, flow rate and geometry of over an order of magnitude. Similarly to a previous <em>submerged</em> jets solution, it is shown that the shape of the arriving profile dictates the stagnation zone wall pressure distribution and radial acceleration. Uniquely for free-surface jets, wider pressure distributions (associated with “flatter” profiles) become affected by the presence of the free surface, leading to increased radial acceleration at the edge of the stagnation zone and a velocity overshoot – beyond the maximal incoming velocity. This is proposed as the mechanism for transition to supercritical flow at the edge of the stagnation zone. The analysis introduces two novel physical parameters, associated with the magnitude of the radial velocity overshoot and measure of arriving profile non-uniformity, to adapt Watson’s uniform wall-jet solution to all other incoming profiles. An interpolation between the adapted stagnation zone solution and Watson’s adapted solution is shown to capture the evolution of various flow aspects: boundary layer growth (including local thinning), free-stream velocity, wall shear, etc. Employing Reynolds analogy, the modified flow solution can be converted to the heat transfer distribution. It is shown to agree well with present and past simulations for horizontal and vertical jets. Moreover, it is seen to capture the emergence of the heat transfer off-center peak, at the edge of the stagnation zone, as well as its growth with flight distance and/or under increasing gravitational influence.

Smooth wall microchannels usually suffers from boiling crisis and local dryout. In this work, we design and fabricate porous microchannel heat sink (Length × width: 20 mm × 10 mm) by sintering copper powders to significantly enhance nucleate boiling and rewetting. However, conventional sintered porous microchannels with powder base would impose large thermal resistance (low thermal conductivity of sintered copper powder, measured as 59 W m^-1 K^-1). Instead, we sintered one layer copper mesh on the bottom surface to significantly reduce the thermal resistance at solid-liquid interface. With the synergistic effect of porous wall and mesh layer, the flow boiling performances can be significantly enhanced. Three different control samples, such as conventional plain wall, sintered porous microchannel with powder base and sintered porous microchannel with mesh base, are fabricated to extensively investigate flow boiling performances. High-speed images of boiling phenomena were recorded to reveal the enhanced nucleate boiling and capillary flow. Bubble dynamics and thin-film evaporation are improved as well. Optimal thermal performance is achieved in sintered mesh porous microchannels owing to the significant decrease of thermal resistance. Compared with CNC plain-wall microchannel, the sintered porous microchannels exhibit significant enhancement in nucleate boiling performance. For example, at 70 mL min^-1, the heat transfer coefficient (HTC) is increased by about 210.3 %, while the critical heat flux (CHF) is enhanced by approximately 48.7 %. More importantly, higher heat transfer performance is achieved in the porous microchannel #2 without additional pressure drop compared to plain wall microchannel.

The KDW-VG model evolved from the KDW model, replacing the KDW model’s power-law function with the more physically robust Mualem–van Genuchten framework. However, existing models often require detailed measurements of water flux versus mobile water content, which limits their applicability under field conditions.

The hydrographs from a soil column with artificial macropores were recorded to calibrate both models. Using the PSO inverse method, unknown parameters were determined by minimizing the error between observed and simulated hydrographs. The finite-difference technique was used to solve both models. The results showed that the KDW-VG model fit the observations more closely, because of the replacement of the power-law function with the Mualem–van Genuchten framework. The dispersive effect was higher at lower rainfall intensities. Overall, the KDW-VG model's parameters exhibited less sensitivity to rainfall variations, which is a key advantage. This research advances computational techniques for modelling mass transfer in environmental systems, specifically addressing preferential water flow and pollutant transport. By improving the accuracy of pollutant transport models while requiring less detailed input data, the method can be applied under field conditions to provide more reliable predictions.

Oscillating heat pipes (OHPs) are highly efficient passive thermal management devices with simple structure, lightweight, and high effective thermal conductivity.

In this work, a one-dimensional numerical model is extended to investigate the OHPs with smooth channels, fully covered capillary wicks, and partially covered capillary wicks. The friction factor governing liquid slug movement is evaluated using the Colebrook-White equation to account for wick-induced surface roughness. Numerical results show that fully covered capillary wicks significantly reduce liquid slug oscillation amplitude and velocity due to increased flow resistance. In contrast, partially covered capillary wicks effectively balance the flow resistance and phase-change driving force. Compared with the OHPs with smooth channels, the liquid slug oscillation amplitude increases by 1 %∼8 % for partially covered wicks and decreases by 34 %∼49 % for fully covered wicks, while the slug velocity increases by 2 %∼6 % and decreases by 21 %∼31 %, respectively. Consequently, partially covered capillary wick OHPs exhibit superior heat transfer performance, with numerical predictions showing a 102 %∼108 % increase in heat transfer power under the same temperature difference.

Based on the orbital locations of these systems, the propellant transfer lines are at an elevated temperature due to radiative heating from the surroundings. Hence, for transferring liquid cryogenic propellant successfully, these transfer lines must first undergo a complete line quenching or chilldown process to prevent any undesired boil-off of the liquid fuel. This transient flow boiling process associated with line chilldown involves complex two-phase spatial and temporal thermal and hydrodynamic interactions between the propellant liquid, vapor, and transfer line wall. In the past, extensive research efforts have been devoted to elucidating the mechanisms of flow regime transition and the corresponding heat transfer behaviors during line chilldown. However, they have been limited by low spatio-temporal resolution in heat transfer measurements and limited transient responses of system hydrodynamic parameters. In this work, in-tube line chilldown experiments using n-Perfluorohexane (n-PFH) were conducted at different mass flow rates and inlet liquid subcoolings in horizontal stainless-steel tubes under terrestrial conditions. Thorough analyses on the high-fidelity experimental data, encompassing wall and fluid temperature, mass flow rate, and pressure, provide fundamental insights into the independent and combined effects of liquid subcooling and mass flow rate on the thermal and hydrodynamic responses and their associated transient flow boiling heat transfer physics. The analysis provides insights into interfacial instability induced re-wetting phenomena, quench front propagation velocities, and local heat transfer coefficients in each flow boiling regime from inverted annular film boiling to termination of nucleate boiling via the transition points of minimum heat flux and critical heat flux. Finally, two key design parameters are developed and analyzed to quantify the efficiency of the entire chilldown process through analysis of the chilldown rate and liquid consumption. This work provides a deeper understanding of the complex transient two-phase flow physics associated with the cryogenic propellant transfer process and provides valuable design and operational guidelines for safe and efficient liquid propellant transfer.</div></div>","PeriodicalId":336,"journal":{"name":"International Journal of Heat and Mass Transfer","volume":"261 ","pages":"Article 128427"},"PeriodicalIF":5.8,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146161470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
