题目：Reflection of Shock Waves and its Optical Visualization
          激波反射及其光学可视化
报告人： Kazuyoshi Takayama
Emeritus Professor of Tohoku University

报告内容摘要：
Reflection of shock waves over wedges and bodies with various configurations is one of the fundamental research topics of shock dynamics, which is not necessarily well resolved. In the Shock Wave Research Center, Institute of Fluid Science, Tohoku University, we have been intensively working for reflection of shock waves in shock tube flows. In this presentation, experimental results of the transitions of reflected shock waves are summarized on the presence of delayed transitions over a wedge and concave and convex wedges; the generation of so-called Neumann reflection; and the three-dimensional reflection over a skewed wedge surface.The image data were collected in diaphragm-less shock tubes with a higher degree of repeatability by using  double exposure holographic interferometry.
