利用热源分布的简化模型，研究了热源分布对内加热诱导自然对流的影响。通过线性稳定性分析，研究了临界瑞利数和临界波数对稳定性的影响。对热源分布的两种极端情况，讨论了产生对流的总热量和对流运动的不对称性。研究了附加底壁加热对临界条件和对流运动不对称性的影响。
The effects of a heat source distribution on natural convection induced by internal heating are studied by using simplified models of the distribution. A linear stability analysis is made to study the effects on critical Rayleigh number and critical wavenumber. The total amount of heat generation to set convection and the asymmetry in the convective motion are discussed for two extreme cases of heat source distribution. Effect of additional bottom wall heating is also investigated on the critical condition and the asymmetry of the convective motion.
