Abstract

In this study, the interaction of the magnetized axisymmetric blunt body with the hypersonic weakly-ionized flow was experimentally investigated. The magnetic interaction induces the shock layer enhancement and it is theoretically expected that the increase of the shock layer is correlated with the interaction parameter. By using a hypersonic flow generated by a expansion tube wind tunnel, we have examined the shock layer enhancement and its correlation with the interaction parameter. For this purpose, the radiating area in the shock layer was measured by a high-speed photography, and various interaction parameters were attained by altering not only the magnetic field strength but also the initial flow density and the model size. The correlation experimentally observed shows a good agreement with the numerically predicted correlation. Therefore it can be concluded that the correlation experimentally observed shows a correlation with the interaction parameter as theoretically predicted. For the comparison, the direct comparison was made using the numerical prediction of the radiating area.
