Numerical Simulation on Boiling Heat Transfer Performance of Bionic Surface by LBM
Boiling heat transfer is one of the efficient heat transfer methods,which is frequently employed in multifarious industries,including the chemical engineering,energy,and thermal man-agement of electronic components.The Lattice Boltzmann Method was applied to study the boiling heat transfer process on bionic surface,and the influence of different surface temperature and wet-tability on the pool boiling was investigated.The results show that the bubble on the hydrophilic surface is more likely to break away from the surface,but the onset of nucleate boiling on the hy-drophobic surface is earlier.By combining hydrophilicity and hydrophobicity to form a bionic hybrid wettability surface,the heat transfer characteristic can be effectively improved.Meanwhile,regu-lating the spacing between hydrophobic regions can achieve efficient heat transfer performance and directional growth of bubbles.
