| 摘 要： | 研究一个液体薄层在热源作用下的流动特征.Pimputakar和Ostrach给出了单热源作用下薄层液体的高度和流场方程。在此基础上具体分析比较了多个热源分布作用下的流动图像随各参数尤其是随热源间距离不同的变化情况,着重讨论产生的分叉现象。

| Abstract: | Convection features in a thin liquid layerwith heating sources is studied in the present paper.Pimputakar and Ostrach gave the thickness equation and flow field of the liquid layer,in the case of a single heating source.This paper examines the variety of the flow image in a thin liquid layer with multiple heating sources,depending on the parameters,especially the distance of the heating sources.The bifurcation phenomenon in the convection is discussed in detail. |
