Some cases of boundary layer flow in a chock tube with insulated walls and a transverse magnetic field are investigated experimentally and theoretically. The configuration is similar to the insulator boundary layer in an MHD generator channel with a loading parameter equal to unity. With argon as the test gas, the experimental results show some cases where the heat flux to the wall is uninfluenced by the magnetic field, and others where a strong effect is observed. A Couette flow calculation, incorporating all relevant physical phenomena and representing the conditions encountered in the experiment, was carried out. The results indicate that the Hall effect has an important influence in such a way that when Hall currents are unrestricted there is little change in the heat flux. The strong interaction observed may be explained by the absence of Hall currents, or possibly by the occurrence of an electron thermal instability predicted by Kerrebrock at high Hall parameters.
