Summary: The lattice Boltzmann method is used to investigate the bubble dynamics on the vertical rough heating wall, considering the conjugate heat transfer process. The results reveal the interaction between bubble dynamics and boiling heat transfer characteristics. It is found that the bubble motion and gas-liquid interface are influenced by the wall thermal conductivity, and the wall mixed wettability has an impact on the conjugate heat transfer behaviors.

Summary: This study investigates the nucleation and growth of condensation droplets on a hierarchical microstructured surface using a two-dimensional phase-change lattice Boltzmann method. The effects of secondary pillar orientation, height, and spacing, as well as wettability and subcooling, on condensation heat transfer are comprehensively discussed. The results demonstrate the significant role of secondary pillars in vapor condensation and show that the hierarchical microstructured surface exhibits enhanced heat transfer ability compared to a single microstructured surface.

Summary: This study investigates the enhancement of heat transfer in a channel with the installation of multiple porous obstacles. A partially heated channel is used, and an array of porous blocks is installed on the channel wall as an effective heat transfer enhancement mechanism. The flow and temperature fields are solved using a well-tuned lattice Boltzmann method. The optimal design of the porous obstacles is obtained by considering the blocks' height, pitch, and permeability of the porous medium as design parameters. The impact of the Darcy number on the thermal performance of the porous block is also studied. The PEC number, which considers both pressure drop penalty and heat transfer rate augmentation, is used as a proper thermal performance evaluation criteria. The results show an optimum value for both blocks' height and pitch, depending on the Darcy number. The study also investigates the impact of obstacle geometry and porous material distribution on the thermal performance of the heat-removing system.

Summary: This study numerically investigates natural convection heat transfer in porous media using the lattice Boltzmann method. The effects of Darcy number, medium porosity, size and aspect ratio of the thermal source on the temperature and flow field in the porous medium are systematically studied. The results show that increasing the Darcy number enhances heat exchange and changes the heat transfer mode from conduction to convection.

Summary: The thermal lattice Boltzmann method is used to simulate cavitation bubble collapse in heating or cooling systems. The results are consistent with Laplace's law and temperature solutions derived from the Rayleigh-Plesset equation. The effects of wall temperature on a collapsing bubble are studied, and the influence mechanism of the micro-jet and the cavitation bubble itself on solid-wall heat transfer, as well as the thermodynamic behavior characteristics of the cavitation bubble collapse near the wall, are obtained. The study also introduces a dimensionless temperature parameter to analyze the heat transfer intensity of the model.

Summary: This study numerically investigates the liquid-vapor phase change and boiling heat transfer induced by a microheater in a fluid using a two-phase lattice Boltzmann method. The effects of gravity force, flow strength, and wall wettability are considered. The results show that, for hydrophilic surfaces, flow motion has little effect on the bubble release period, while for hydrophobic surfaces, bubble departure is significantly accelerated by the shear flow.
