目的と概要
It has been widely recognized that the schlieren technique is one of the most useful method to visualize the density gradients in a transparent medium. One of the most popular applications is in the experimental study of supersonic flows because of its simple optical arrangement with a high degree of resolution and ability to easily observe such structures as shock waves, Prandtl-Meyer compression and expansion fans in supersonic jet flows. Also, this method for flow visualization does not require the introduction of additives into the flow field and is capable of providing useful qualitative information on the variations in fluid density, temperature, and static pressure. The purpose of this course is to provide students with a clear explanation of the physical phenomena encountered in compressible flows, to develop and understand optical measurements of compressible flows.
