摘　　要：自然对流是流体流动和传热的最重要形式之一,如今在矩形腔体对流换热的研究中,科学家进行一系列理论和实验数值求解来探究对流传热中的传热规律和流体运动过程,本文对最近一段时间的矩形腔内自然对流研究以及对这些研究的数值实验技术进行归纳总结。这些研究在各种参数(如瑞利数和普朗特数,腔体倾角,热特性等)的影响下,并考虑了具有不同初始条件和边界条件,热源位置以及流体介质和壁的辐射特性的腔体外壁的多种配置。最后,为所研究矩形腔体内自然对流传热领域的未来研究提供了一些建议。Natural convection is one of the most important forms of fluid flow and heat transfer. Nowadays, in the study of convection heat transfer in rectangular enclosures, scientists have carried out a series of theoretical and experimental numerical solutions to explore the heat transfer laws and fluid motion processes in convective heat transfer. In this article, the recent researches on natural convection in rectangular enclosures under numerical experiment technology were summarized. These studies, under the influence of various parameters (such as Rayleigh number and Prandtl number, enclosure inclination, and thermal characteristics, etc.), consider the different initial and boundary conditions (such as the location of the heat source, the radiation characteristics of the fluid medium and the wall, and various configurations of the outer wall of the enclosures). Finally, some suggestions are provided for future research in the field of natural convection heat transfer in the studied rectangular enclosures.
