Is two-dimensional oblique stagnation-point flow unique?

Abstract

The problem of two-dimensional oblique stagnation point flow is reviewed and the two solutions which exist in the literature are reconciled. It is found that a family of solutions exists for the problem, but that a unique solution can be obtained by examining the second order terms in the asymptotic expansions at infinity. The slope-ratio constant is verified to be independent of the incidence angle of the impinging stream. A second ratio involving the locations of maximum pressure along the wall and vanishing tangential stress is shown to share the same incident angle independence.
