Abstract : The viscous flow near the stagnation point on an interface between two liquids with different densities is studied. The use of a model allows some fairly general results to be readily obtained as a result of a mathematical analysis. Moreover, although the model is obviously not in full accordance with re-entry phenomena, it is believed that it is not over-simplified, and that solutions of real problems obtained on the basis of the results of the present study will be at least qualitatively correct. Equations governing the stated problem can be transformed to those describing the stagnation point flow at a rigid wall, but the boundary conditions are different. Results concerning the velocity and temperature fields based on a numerical integration of these equations are given. Also presented approximate formulas for heat transfer, displacement thickness, momentum thickness, boundary layer thickness, and temperature layer thickness. (Author)
