| 摘 要： | 对具有内热源方腔的稳态层流耦合自然对流换热进行了三维的数值模拟，采用的模拟代码基于连续介质计算力学的开源库OpenFoam，解决了自然对流换热与固体传热的耦合问题．Rα数的变化从10^5到10^9．对外壁面为常温、方腔内充满含体积热源流体的自然对流计算结果表明，温度场、速度场与非耦合的工况有很大差异．

| Abstract: | This work was focused on the numerical simulation of steady, laminar, conjugate natural convection in a square enclosure containing volumetric hear sources. Simulations were made using the codes developed from open software library OpenFoam for computational continuum mechanics, The codes could perform conjugate natural convection with solids with Rayleigh number was varied from 107 to 109. Outsides of walls were kept in constant temperature and the fluid containing volumetric hear sources filled in the enclosure. The results showed a significant change in the temperature and velocity fields compared with the non-conjugate conditions. |
