本文通过理论分析、数值模拟与实验研究的综合，研究了粘性耗散及变物性对多孔介质中对流换热的影响。发现：用理想的等热流边界条件可以较好地数值模拟等热流边界条件下多孔介质中的对流换热；在实际可实现的参数条件下，粘性耗散对多孔介质中对流换热的影响不大；油的变物性对换热的影响很大—热流密度越高，对流换热越强。
In this paper, through theoretical analysis, numerical simulation and experimental study, the effects of viscous dissipation and variation on the convective heat transfer in porous media are studied. It is found that convective heat transfer in porous media under ideal heat flux boundary conditions can be better numerically simulated by the ideal isothermal boundary conditions. The influence of viscous dissipation on convective heat transfer in porous media is not affected by the practically achievable parameters Large; oil variable nature has a great influence on heat transfer - the higher the heat flux, the stronger the convective heat transfer.
