用Gong-Cheng格子Boltzmann方法汽液相变模型数值研究了具有单个和多个微孔的粗糙表面上的池沸腾传热,通过数值模拟得到了含有多个微孔的粗糙加热面上从自然对流区直至膜态沸腾区的池沸腾曲线.模拟结果表明亲水微孔和疏水微孔中存在不同的汽泡成核和生长形态.存在一个临界微孔深度,使得汽泡脱离频率在该处跃升,从而提高沸腾传热量.在粗糙表面上,汽-液-固三相接触线处具有最低的局部温度和最高的局部热流密度.“,”Boiling heat transfer on rough surfaces with single cavity and multi-cavities is numerically investigated by Gong-Cheng lattice Boltzmann models for liquid-vapor phase change heat transfer. Boiling curves from natural convection regime to film boiling regime on surfaces with multi-cavities are numerically obtained. Simulation results suggest that hydrophilic and hydrophobic cavities have different bubble nucleation and growth characteristics. There exists a critical cavity depth, beyond which the bubble departure frequency jumps and therefore enhancing boiling heat flux. The three-phase contact line region exhibits the lowest local temperature and the highest local heat flux.
