可控肥皂膜气柱界面与激波相互作用的实验研究
摘要
Abstract
A simple method of generating gas cylinder is proposed by using the soap film tech-nique.The formed interface is free of supporting mesh and the initial condition can be well con-trolled .Experiments are then carried out in a horizontal shock tube for a planar shock wave inter-acting with a two-dimensional or three-dimensional cylinder using high-speed schlieren technique. It is found that the schlieren images have fewer disturbing waves and the evolving interfaces are more symmetric comparing with the results in literature.Special attention is given to the three-dimensional effects caused by the minimum surface feature on the interface evolution and it is in-dicated that the interface evolving rate of three-dimensional cylinder is slower than that of two-di-mensional cylinder.This work will facilitate more understanding about the three-dimensional effect on the development of the Richtmyer-Meshkov instability.关键词
