有关多层流体对流的研究

ON THE RESEARCH OF MULTI-LAYER FLUID CONVECTION

简述多层不相混流体系统的研究发展，尤其是在空间材料生长过程中的应用；介绍多层流体系统内流体对流及传热现象，以及利用理论分析、实验研究和数值模拟方法研究二层及三层流体内的自然对流及热毛细对流的成果。

Development of research on the system of multipleimmiscible fluid layers, especially in the application of a spacecrystalgrowth process technique, is reviewed briefly. This paperdescribes the phenomena of fluid convection and heat transfer ina multilayer fluid system, and presents the results of theoreticalanalyses, experimental research and numerical simulation on the naturalconvection and thermocapillary convection in a fluid with two or threelayers.The features of hydrodynamic control of the melt encapsulatedfluid by an encapsulant layer and the stability of system are also discussed.
