Abstract

The numerical simulation for the magnetic interaction in the hypersonic flow around the double cone model predicts that as a result of the interaction, the shock wave generated by the second cone is primarily affected and is shifted away from the model surface, affecting the separation bubble. Furthermore, because of this interaction, the separation bubble is enhanced. To validate the numerical prediction, we have conducted an experimental investigation by mean of the expansion tube facility which enables us to generate a high speed flow of 12 km/sec. For measurement, the sequential images of the flow around a model were recorded. The experimental result agrees with the numerical prediction at least qualitatively. As a matter of fact, in the experiment, we can observe the effect of the applied magnetic field more clearly than expected. The flow control accomplished by the present magnetic interaction is qualitatively equivalent to the one accomplished by the increase of the half-angle of the second cone which may represent the aerodynamic control surface. In this context, the present magnetic interaction may have a possibility to replace the mechanical aerodynamic control surface.
