ON THE FLOW PAST A SEMI-INFINITE FLAT PLATE,
JOHNS HOPKINS UNIV BALTIMORE MD DEPT OF MECHANICS
The Navier-Stokes equations for two-dimensional flow are linearized around a dominant uniform stream velocity. The concept of field modes in fluid mechanics is then applied to the often-treated and well-known problem of viscous incompressible flow over a semi-infinite flat plate fixed in an unbounded uniform stream. One of the results that emerges from this novel treatment of an old problem is that the usual notion of a displacement thickness leads naturally to a displacement boundary beyond which the streamlines of the viscous flow past the flat plate are indistinguishable from the streamlines due to potential flow past this boundary.
