Abstract:

The base pressure problem of a transonic flow past a backward facing step in the axisymmetric configuration has been examined. The invisid flow field is generated from an equivalent body with a characteristic parameter and the value of this parameter is determined through the viscous flow analysis. The full axisymmetric potential equation is solved by numerical relaxation while the viscous flow is analyzed through integral formulations. The point of reattachment behaves as a saddle point singularity. The base pressure results are in reasonable agreement with available experimental data. Author
