本文采用格子Boltzmann方法对平行平板通道内多个受热障碍物的共轭换热进行了数值模拟。目的是研究有关的热物理参数和几何参数对障碍物周围局部努塞尔数的影响。结果表明，增大障碍物与流体的导热比，减小壁面与障碍物的导热比，可使障碍物周围的局部努塞尔数增大。将本研究的结果与传统数值方法得到的结果进行了比较，两者吻合较好。
In the present study, lattice Boltzmann simulation of conjugate heat transfer from multiple heated obstacles mounted in a walled parallel-plate channel is carried out. The aim is to investigate the effects of the pertinent thermophysical and geometrical parameters on the local Nusselt number around the obstacle's periphery. The result showed that increasing the obstacle to fluid thermal conductivity ratio and decreasing wall-to-obstacle thermal conductivity ratio results in increasing the local Nusselt number around the obstacle's periphery. The results of the present study are compared with those available from the conventional numerical methods, and good agreement is observed.
