Boundary Layer Flow of Air Over Water on a Flat Plate
Abstract
A non-similar boundary layer theory for air blowing over a water layer on a flat plate is formulated and studied as a two-fluid problem in which the position of the interface is unknown. The problem is considered at large Reynolds number (based on chi), away from the leading edge. We derive a simple non-similar analytic solution of the problem for which the interface height is proportional to chi to the l/4 power and the water and air flow satisfy the Blasius boundary layer equations, with a linear profile in the water and a Blasius profile in the air. Numerical studies of the initial value problem suggests that this asymptotic, non-similar air-water boundary layer solution is a global attractor for all initial conditions.
