提出了将轻微可压缩流动模型扩展到封闭在空腔中的理想气体二元混合物的双扩散对流的模型。问题公式基于低马赫数近似，并且不调用不渗透表面假设。本文的主要目的是陈述一个新的问题公式，并对一些重要结果进行分析，这些结果表明密度变化对纯热或纯溶液对流瞬态解的影响。在稳态时，结果表明，传热传质类比可以应用于参数范围大于通常考虑的参数范围的非稀释混合物。引用本文：H. Sun、G. Lauriat、C. R. Mecanique ••• (••••)。
An extension of a slightly compressible flow model to double-diffusive convection of a binary mixture of ideal gases enclosed in a cavity is presented. The problem formulation is based on a low Mach number approximation and the impermeable surface assumption is not invoked. The main objectives of this paper are the statement of a new problem formulation, and the analysis of some significant results showing the influence of density variations on transient solutions for pure thermal or pure solutal convection. At steady-state, it is shown that the heat and mass transfer analogy may be applied for non-dilute mixtures at parameter ranges larger than those usually considered. To cite this article: H. Sun, G.
