| 摘 要： | 本文对前驻点加热圆柱绕流场进行了可视化实验研究．结果表明，前驻点加热时，在不可压缩流体中由于产生了较大的局域压力提供的热驱动力，在该处产生间歇性猝发反向流动，不仅改变了驻点区的流动结构，并影响整个流动拓朴结构，还改变了分离点、前驻点的位置，提高了流动稳定性，该结果有助于定性解释加热减阻机理．

| Abstract: | This paper presents a visualizational experimental study about flow around a circular cylinder with heating front stationary point.The results proved that heating front stationary point produces large thermo-drive force in incompressible nuids,which induces intervalic reverse flow and variates the flow topological structure,then influences on position of stationary point and separational point and flow stability.These results may help to explain mechanism of thermo dray reduction. |
