GASEOUS RADIATION IN HYPERSONIC STAGNATION POINT FLOW

Abstract

The problem of gaseous radiation in a hypersonic stagnation point flow was investigated. The experiments were performed in a 3-in. diameter buffered shock-tube. The investigation covered the following phases: (1) photographic study of luminous bow-shock regions; (2) total light radiation measurements; (3) spectral light intensity measurements; (4) spectrographic study of radiating species. The photographic study yielded information regarding standoff distances in the shock tube flow. These measurements were correlated with various theroetical predictions. The light intensity measurements were made at the stagnation point of two hemisphere cylinders 3/8 in. and 3/4 in. in diameter. The test results discussed in this paper indicate that light intensity measurements made with two models of different characteristic dimensions can be used successfully to obtain this information.
