Abstract

A study is made of the effect of thermal radiation on the propagation of plane shock waves produced by an infinite, plane and moving wall. Governing equations of one-dimensional, nonsteady and radiating gas flow are formulated, and solutions are found by using the perturbation technique and the method of characteristics. To display the essential features of the radiation effect a few cases, optically thick gas, optically thin gas, perfect absorbing wall, and perfect reflecting wall, are studied in detail. For the case of large time and a perfectly absorbing wall, the profiles of temperature, pressure, and density (or shock structure) resemble those of steady radiation-resisted shock waves. Application of these solutions to the shock tube problems is also discussed.
