Summary: Experimental studies are conducted to investigate the non-isothermal evaporation and heat transfer of water droplets and films on structured walls. The results show that the textured surfaces can change the wettability and enhance the heat transfer, leading to an increased evaporation rate. Furthermore, self-organization of colloidal aqueous solution films under local heating is observed.

Summary: A general gas-phase energy formulation can be obtained independently from the species diffusion transport modeling while incorporating multi-species enthalpy diffusion terms. The choice of specific heats characterizes the inclusion or not of multi-species enthalpy diffusion effects. The proposed energy formulation is evaluated by conducting simulations for droplets of multiple fuel compositions in varied atmospheric conditions to represent spray combustion scenarios and concludes on its need and ease of use.

Summary: Surface modification using laser texturing shows great potential in enhancing heat transfer and increasing critical heat fluxes during pool boiling on metal surfaces. The experiments demonstrate that the laser-textured surface significantly improves heat transfer compared to untreated and polished surfaces. High-speed video recording analysis reveals that laser treatment leads to increased nucleation site density and frequency, as well as reduced bubble departure diameter.

Summary: This paper investigates the heat and mass transfer characteristics of liquid droplet evaporation under the influence of gravitational force, particularly on surfaces with special wetting properties. A unique substrate was created using a special technique to physically simulate the interaction between droplets and the surface at any inclination angle. The study reveals that suspended and sessile droplets exhibit fundamentally different evaporation dynamics, with suspended droplets having higher temperatures and evaporating nearly 30% faster.

Summary: We investigated droplet evaporation on heater surfaces with different thermal conductivities using the phase change lattice Boltzmann model. The evaporation curves revealed four regimes: film evaporation, nucleate boiling, transition, and Leidenfrost. We found that higher thermal conductivity does not always accelerate droplet evaporation. In transition regime, lower thermal conductivity enhances droplet evaporation by triggering the second contact between droplet and heater.

Summary: The experimental findings present the convective heat transfer in drops and films of fuel microemulsions heated on hot surfaces, analyzing features and characteristics of vaporization and coalescence of the dispersed phase of microemulsions using optical microscopy. The results show that the evaporation rate of the dispersed phase largely depends on the emulsifier and distilled water concentration, with droplet size decreasing linearly with temperature below 80 degrees C and increasing above 80 degrees C. The number of large coalesced droplets decreases linearly with time, more intensively at surface temperatures above 80 degrees C.

Summary: Experimental studies on evaporation, crystallization, and heat transfer in a droplet of NaCl/H2O solution have shown that supersaturation and heating of the wall significantly affect the process. Four characteristic modes of evaporation and crystallization are distinguished, with the ratio of the crystallization rate to the evaporation rate being highly variable and regulated by Marangoni convection. The data obtained provide insights for the development of high-temperature crystallization concepts in the presence of intense Marangoni flow.

Summary: Forced convection increases the dissociation rate of gas hydrate, with two typical decay modes during the dissociation process of complex gas hydrate. The optimal air velocity for increasing combustion efficiency falls within the range of 0.75-1.25 m/s. However, exceeding a velocity of 3.5 m/s leads to the cessation of fuel combustion.

Summary: This article presents a multifield asymptotic homogenization scheme for analyzing Bloch wave propagation in non-standard thermoelastic periodic materials. The proposed method derives microscale field equations, solves recursive differential problems within the unit cell, establishes a down-scaling relation, and obtains average field equations. The effectiveness of this approach is validated by comparing dispersion curves with those from the Floquet-Bloch theory.

Summary: This paper proposes a novel triple-gradient phononic acoustic black hole (ABH) beam that strategically manipulates multiple gradients to enhance its performance. The study reveals that the ABH effect is not solely brought about by the thickness gradient, but also extends to the power-law gradients in density and modulus. The synergistic development of three different gradient effects leads to more pronounced and broader bandgaps in PCs.

Summary: This study numerically investigates the behavior of an ultrasonically driven gas bubble between two parallel rigid circular walls with a cylindrical micro-indentation in one wall. The primary objective is to determine the conditions that facilitate the removal of particulate contamination from the indentation using the bubble jet. The study found that the bubble jet can effectively remove contamination from the indentation for certain ranges of indentation diameter, but becomes less effective for larger indentation diameters.
