Design of a High Resolved Schlieren System

Abstract:

A schlieren system with high time and space resolution was developed to diagnose the hypersonic flow field with high speed, low density and intensive shock interactions. The key technique of color filter used for color schlieren was developed. The time resolution reached to 100ns and the space resolution reached to 0.1mm. In shock tunnel with Mach 5, bow shock controlled by single laser pulse was investigated with the schlieren system, and the interaction of oblique shocks generated by double ramps was detected with color schlieren. The complex flow fields are clearly exploded, which proves that the schlieren system designed in this paper supplies an efficient method in the diagnostics of hypersonic flow field.
