Abstract:

T HE PROBLEM OF STEA Y, INVISCID, MAGN TOGASDYNAMIC FLOW PAST AN UNYAWED INFINITE CONE IS TUDIED FOR THE SPECIAL CASE OF AN APPLIED MAGNETIC FIELD ALIGNED WITH THE FREE STREAM. Two special c ses are considered, the con uctivit of the gas ahead of the shock wave having a value of zero and a value of infinit . In bot cases, the con uctivity of t e gas between the hock wave and t e cone i ssume to be infinite, and it is assumed t ere are no currents ahead of the shock wave. when these two a sumptions are satisfied, the two cases are the same. Solutions to the problem are found for two distinct flow regimes, using an incompressible approximation to the low between the shock and the body. The firs flow regime is a modification of the ordinary gasdynamic flow, and occurs for supersonic and superalfvenic freestream conditions. The second flow regime is essentiall different from the ordinary gasdynamic flow, being characterized by a forward-facing shock wave, and occurs for subsonic and subalfvenic freestream condition , but with the restric ion that the sum of M squared plus A squared exceed unity, wh re AND A are the Mach number and Alfven number, respectively, of the flow.
