Book Description
A hypersonic-wind-tunnel nozzle concept which incorporates a hot-core flow surrounded by an annular flow of cold air offers a promising technique for maximizing the model size while minimizing the power required to heat the test core. This capability becomes especially important when providing the true-temperature duplication needed for hypersonic propulsion testing. Several two-dimensional wind-tunnel nozzle configurations that are designed according to this concept are analyzed by using recently developed analytical techniques for prediction of the boundary-layer growth and the mixing between the hot and cold coaxial supersonic airflows. The analyses indicate that introduction of the cold annular flow near the throat results in an unacceptable test core for the nozzle size and stagnation conditions considered because of both mixing and condensation effects. Use of a half-nozzle with a ramp on the flat portion does not appear promising because of the thick boundary layer associated with the extra length. However, the analyses indicate that if the cold annular flow is introduced at the exit of a full two-dimensional nozzle, an acceptable test core will be produced. Predictions of the mixing between the hot and cold supersonic streams for this configuration show that mixing effects from the cold flow do not appreciably penetrate into the hot core for the large downstream distances of interest.

Book Description
This volume contains the proceedings of a symposium held at the University of Toronto in June 1969. The symposium consisted of six sessions; each containing an invited paper, followed by six contributed papers reporting on recent, relevant research and development. The topics are: a review of research problems in basic shock tube flows and the possibilities for the shock tube in the future; driving techniques; explosive drivers; theoretical and experimental research in electromagnetic shock tubes; chemical kinetics and spectroscopy; and a review of shock tube diagnostics, instrumentation and fundamental data as well as the measurement of physical quantities.
