This study primarily examines how various parameters of hydrophilic pillars with partial wettability manipulation affect droplet nucleation, growth and departure, as well as heat transfer capacity. The parameters explored include pillar height, base width, center-to-center spacing, and contact angles of both hydrophilic and hydrophobic regions. The results indicate that under fixed pillar dimensions and contact angles, a smaller center-to-center spacing increases the possibility of droplet coalescence through liquid bridge formation, which however hinders droplet removal and reduces heat transfer efficiency. Both excessively tall and overly short hydrophilic pillars decrease surface heat flux, while the former is due to increased droplet retention and inhibited detachment, and the latter is caused by insufficient hydrophilic area. Reducing the contact angle of either hydrophilic pillars or hydrophobic regions can improve overall heat transfer efficiency by increasing the heat flux. Furthermore, replacing the top walls of pillars from hydrophilic to hydrophobic facilitates the droplet departure, thereby improving the heat transfer performance. This numerical analysis contributes to a further understanding of vapor condensation behavior on hybrid wettability surfaces under phase-change conditions.</div></div>","PeriodicalId":339,"journal":{"name":"International Journal of Multiphase Flow","volume":"195 ","pages":"Article 105528"},"PeriodicalIF":3.8,"publicationDate":"2025-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145517907","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}

This work performs detailed experiments in twelve horizontal bubbly flow conditions, measuring the void fraction, bubble velocity, and liquid velocity with local conductivity and Pitot-static probes. With this information, novel trends in the relative velocity are discussed. The relative velocity is found to be negative throughout the pipe, in contrast to vertical flow. It is found to be most negative in the bubble cluster at the top of the pipe, but remains negative even as the void fraction approaches zero. With the experimental database established, a mechanistic model is proposed for the relative velocity, based on the wake interactions between bubbles and liquid phase turbulence. The model is able to predict the presented dataset within 15 %. The gas velocity is estimated by combining the relative velocity model and a 1/7^th power profile for the liquid, which allows for comparison against data in literature where no relative velocity data is available.

The results show that higher upstream pressure substantially intensifies cavitation, while the presence of dissolved CO₂ lowers the pressure threshold for cavitation inception and amplifies cavitation activity. The micro-step chip (Reactor 1) presented more intense cavitation and a greater vapor void fraction than the long-diaphragm chip (Reactor 2) across all conditions. Notably, dissolved CO₂ suppressed high-frequency bubble-collapse fluctuations and induced a transition from violent cloud-shedding cavitation to a stable, continuous bubbly flow regime. Additionally, cavitation facilitated significant CO₂ degassing, removing up to ∼30% of the dissolved gas in Reactor 1 (versus ∼11% in Reactor 2) under the similar conditions. The results also show that temperature significantly influenced CO₂ removal efficiency, with the highest elimination (52%) occurring at 25°C, where high gas solubility and low vapor pressure were optimally balanced.

Viscoelastic turbulence drag reduction is one of the means of reducing drag for underwater vehicles. During the use of this drag reduction agent, the movement of bubbles around the vehicle in the viscoelastic fluid is inevitable. Therefore, the dynamics of the cavitation and air bubbles in sea-based viscoelastic fluids were experimentally investigated in present work. The results demonstrate that increasing seawater salinity and viscoelastic fluid concentration reduces cavitation bubble size, under identical conditions. The bubble lifetime increases with bubble size, although it is markedly shorter in seawater compared to other media.
