Abstract
The response of gas (air) bubbles in a spherical cluster to an increase in the pressure of the surrounding liquid (water) is considered. Consideration is carried out only until a bubble in the cluster disintegrates or collides with another bubble. The influence of the amplitude of the increase in the liquid pressure, as well as the position of the bubbles in the cluster and the interaction between the bubbles, is studied. The centers of the cluster bubbles are located at the nodes of a cubic grid, one of which is in the center of the cluster. The effect of the interaction of bubbles is assessed by comparison with the response of a single bubble. The cluster consists of 123 bubbles, the liquid pressure is 1 bar. Initially, the bubbles are spherical with a radius of 0.1 mm, the cluster radius is about 3 mm. A discrete model is used, in which, together with the radial oscilations of bubbles, their movements in the liquid and their small deformations are also modeled. It is established that the maximum pressure in the bubbles, reached before the destruction or collision of any of them, is realized when the liquid pressure increases by 10 bar and turns out to be approximately 6500 times greater than their initial pressure and approximately 30 times greater than the response of a single bubble.

Abstract
The flow of an aqueous film along a vertical heater was studied for Reynolds numbers of 33, 50, and 105 and initial temperatures T0 = 15, 23, 30, and 40°С. It was shown that the amplitudes of the zigzag motion of the rivulets increased with increasing heat flux density. The most intensive growth of amplitudes was observed with the development of thermocapillary instability in the upper part of the heater. For high heat fluxes, when the amplitude of the zigzag motion reached a sufficiently large value, interaction of the rivulets began. Several types of interaction of rivulets on the surface of the heated liquid film were distinguished. It was shown that the appearance of a thermocapillary structure in the upper part of the heater led to movement of rivulets and an increase in the heat transfer intensity.

Abstract
This paper proposes a modified effective length method for calculating heat fluxes in complex geometries in a three-dimensional formulation when moving in the atmosphere at high speeds and describes its software implementation. The method, on the one hand, does not require huge computational costs to obtain results, and on the other, demonstrates stable operation in complex geometries.

Abstract
The authors studied the dynamics of thinning of the zona pellucida (ZP) in mouse embryo as a result of laser-assisted hatching performed at the blastocyst stage. Mouse embryos previously subjected to a freeze–thaw cycle (cryo-embryos) were selected as model embryos. For ZP microsurgery, femtosecond laser pulses were used (radiation wavelength 512 nm, pulse duration 100 fs, intensity 2.5 TW/cm2). The thickness of the ZP was measured before microsurgery at the blastocyst stage (~E3.5, i.e., 3.5 days of embryonic development) and at the hatching stage (~E5). It was found that the ZP of control group embryos (cryo-embryos not subjected to laser exposure) thinned more strongly (from 6.6 (E3.5) to 4.9 µm (E5)) compared to experimental embryos after the laser-assisted hatching procedure (from 7.1 ( E3.5) to 6.4 µm (E5)). In both the first and second cases, changes in ZP thickness were statistically significant. The results were compared with data for “fresh” embryos not subjected to cryopreservation. There was no pronounced effect of ZP hardening in cryo-embryos compared to fresh embryos. The use of the laser-assisted hatching procedure for cryo-embryos made it possible to increase the probability of successful hatching compared to embryos in the control group from 38.5 to 52.5%.

Abstract
The parameters of heat transfer at compressible gas flow with a favorable pressure gradient have been experimentally studied. The heat transfer coefficients and the temperature of thermally insulated (adiabatic) wall are determined using the transient heat transfer method. To estimate the degree of flow laminarization, the results obtained are compared with the known dependences for the turbulent boundary layer developing on a plate in a zero-pressure gradient flow. Some regularities of the effect of flow acceleration on the heat transfer law are revealed for the studied configurations of supersonic nozzles.

Abstract
The spontaneous boiling-up kinetics of liquid alkanes (methane, ethane, and propane) saturated with one of the following gases: helium, hydrogen, nitrogen, or methane is studied. The solution nucleation rate temperature, baric, and concentration dependences in the interval (104–108) m–3 s–1 are determined using the mean lifetime method. The measurements were carried out at pressures of 1–2 MPa and volatile component concentrations up to 6 mol %. The experimental results are compared with the classical nucleation theory in a macroscopic approximation. In contrast to pure liquid and liquid saturated with helium or hydrogen, the attainable superheating temperatures of solutions containing nitrogen or methane as a dissolved substance exceed their theoretically predicted values. The factors causing this mismatch are discussed.

Abstract
We present the results of a three-dimensional numerical simulation of the dynamics of a falling film of a mixture of refrigerants, 0.9 mol fraction R21 + R114, considering the liquid flow along the outer lateral surface of a round vertical cylinder for a Reynolds number of 104 and contact angles of 10°, 30°, 50°, 70°, and 90°. The simulation was carried out using the volume of fluid (VOF) method in the OpenFOAM software. The contact angle has a significant effect on the area of the wetted surface due to a change in the modes of liquid falling down the cylinder. The following flow modes are identified: continuous film, stable jet mode, cascade jet mode, and massive jet mode. These modes are similar to the modes of fluid flow on horizontal tubes.

Abstract
The work shows the dependence of the moment of the discharge-activated zone ignition and the moment of self-ignition of the fuel mixture in the region ahead of the combustion wave front on two parameters: the crankshaft rotation angle at which the discharge was initiated and the specific energy input into the streamer channel. It is shown the necessity to take into account the change in pressure in the cylinder due to the movement of the piston in order to more accurately determine the optimal ignition limits of the activated zone and the occurrence of self-ignition. When modeling, the inhomogeneous formation of chemically active particles associated with the streamer and multi-pulse nature of the discharge was taken into account.

Abstract
The study considers generation of a dispersed coolant flow; the size distribution of droplets in the flow depending on the flow rate, pressure, and thermophysical properties of the coolant; the breakup and coagulation of droplets; and droplet size ranges resistant to breakup. A computer code for calculating the evolution of the spray cone parameters was developed based on the momentum equation and distribution of droplets along the radius in the flow at the atomizer nozzle.
