The flow within a shock wave is governed by the relaxation times of the molecular degrees of freedom. Advances in shock tube design and instrumentation have made it possible in recent years to resolve all the relaxation times including the shortest, corresponding to the translational degree of freedom. The shock tube thus becomes an important tool for critical experiments in the study of the range of applicability of the Navier-Stokes equations and similar approximations and of the character of solutions of the Boltzmann equation. Significant progress has been made recently in the understanding of the most obvious such problem, the flow within a shock in a monatomic gas. Theory and experiment are now in substantial agreement and the over-all process of energy exchange is understood. Problems connected with shock wave reflection from real walls have made progress but a host of problems remain to be studied including surface interaction effects. The extension of this type of shock tube research to more complicated systems, reacting gases, gas mixtures, and the like has begun and some progress can be reported. Recent experimental progress is illustrated by a number of measurements made at GALCIT in the 17- and 6-in. shock tubes. Sophistications in shock tube design and instrumentation will be discussed.
