Oscillating stagnation point flow
Abstract
A solution of the NavierStokes equations is given for an incompressible stagnation point flow whose magnitude oscillates in time about a constant, nonzero, value (an unsteady Hiemenz flow). Analytic approximations to the solution in the low and high frequency limits are given and compared with the results of numerical integrations. The application of these results to one aspect of the boundary layer receptivity problem is also discussed.
