Development of a tracer-spark technique for the study of hypervelocity flow fields by James Burley Kyser( Book )

2 editions published in 1964 in English and held by 2 WorldCat member libraries worldwide

A technique was developed for the mapping of velocity fields, with particular application to testing in a spark-heated hypersonic tunnel. Data were obtained in the form of photographs of sparks struck through the flow field under study. Instrumentation to initiate the sparks in the flow was designed and fabricated, and its performance has been studied analytically and experimentally. Velocity profiles were obtained in the empty test section with a high degree of success. Attempts to measure velocity profiles in wakes were not as successful, however. (Author)
Measurements of pressure and speed of flow in a spark-heated hypersonic wind tunnel by Krishnamurty Karamcheti( Book )

1 edition published in 1962 in English and held by 1 WorldCat member library worldwide

The nature of the flow and state of the gas in the nozzle and test section of the Stanford spark-heated hypersonic wind tunnel was studied. Attention is given only to the pressure and speed-of-flow measurements. Results are presented for pitot pressures and wall static pressures. The speed of flow in the test section is derived from measurements made by spark-schlieren photographs of a disturbance created in the flow by means of a spark discharge. On the basis of these measurements, it is concluded that the actual stagnation enthalpy of the stream is likely to be different from the enthalpy calculated according to current practice. As a consequence, it is shown that serious errors may occur in the calculated values for the state of the flow, and in theoretical estimates of quantities such as stagnation-point heat-transfer rates.

To prevent the larger second throat area required for starting a supersonic wind tunnel penalizing the performance during the entire run, a diffuser was constructed with a movable centerbody. After the normal shock had been swallowed during starting, the centerbody was moved forward, thus constricting the flow area at the second throat. This allowed the normal shock, or shock system, to occur at a lower Mach Number, and therefore, reduced the losses
