Abstract
Shock reflection hysteresis in a low density, axisymmetric underexpanded air jet is examined using a Navier-Stokes flow solver. Jets of this type are found in a number of applications e.g. rocket exhausts. The existence of a dual solution domain where either regular or Mach reflection may occur within the complex plume structure is predicted. This is in agreement with experiment where the same phenomenon has been observed for a nitrogen jet. The results of the computational study are used to examine the structure of the plume, and are compared with experimental data where available. The plume structure is complex, involving the interaction of several flow features, making this a demanding problem. A quasi-steady approach is employed in order to calculate the entire hysteresis loop. Included in this report is a review of the two dimensional shock reflection hysteresis problem. Some recommendations are made for further study of this type of flow.
