Title: Frozen-plasma boundary-layer flows over adiabatic flat plates

The boundary-layer equations for a partially ionized frozen flow over a flat plate has been solved using a new approach in which the problem is reduced from a two-point boundary value problem to a Cauchy problem, thus offering a simple, stable, and relatively inexpensive solution technique. The method is applied to a strong shock-induced argon flow over an adiabatic flat plate. The dependence of the flow inside the boundary layer on the Prandtl number Pr, and Lewis number Le, and on the exponential dependence n of the density viscosity product on the temperature are explored, and it is found that while Pr and n strongly affect the obtained flow field, the influence of Le is negligibly small.
