Abstract:

The flow field in the neighborhood of the discontinuity or a sharp corner is divided into two regions The flow upstream of the discontinuity which is obtained by standard techniques, and that of downstream which is obtained by standard techniques, and that of downstream which is obtained by expanding both the super sonic and subsonic flow fields upstream of the discontinuity inviscidly around the corner. Downstream of the discontinuity, the flow is represented by a viscous nonsimilar sublayer which starts at the discontinuity, and by a viscous shear layer which has the profiles immediately downstream of the discontinuity as initial conditions. Based upon this flow model, analysis has been developed using the inner and outer expansion techniques. The treatment of the laminar analysis is improved and the technique of application of this model is extended to include turbulent and transitional flow downstream of the corner. Finally, the results are compared with some of the experimental data available in the literature. It is indicated that good agreement was obtained.
