Two Effects of Diaphragm Bulge on Shock Tubes

摘要: A computational study is presented that has uncovered two important effects in shock tube flows. They occur because the diaphragm to support a static load before it breaks. This usually deforms rupture. These can have significant consequence both reflected-shock tunnels and expansion tubes. The first effect bulge causes wave be propagated across repeatedly reflected at axis wall. second contact surface rolls up form vortex ring. sign of vorticity ring depends on temperature ratio diaphragm.
