Flow Induced by the Impulsive Motion of an Immite Flat Plate in a Dusty Gas. The problem of
flow induced by an infinite flat plate suddenly set into motion parallel to its own plane in an incompressible
dusty gas is of considerable physical interest in its own right as well as because of its close relation to the
non-linear, steady (constant-pressure) laminar boundary layer. Its solution provides complete and exact
information about modifications of the boundary layer growth and skin friction due to particle-fluid
interaction. Moreover, it provides a basis for judging the accuracy of approximations which have been
employed in more complex problems of viscous fluid-particle motion. The uncoupled thermal Rayleigh
problem for small relative temperature differences is directly inferred and this answers questions about the
modifications of the surface heat transfer rate and about the possibility of similarity with the velocity
boundary layer. Similarity is possible when, in addition to a Prandtl number of unity, the streamwise
relaxation processes are also similar
