Abstract:

The transport and deposition of fine particles in a boundary layer of impulsive flow over a flat plate have been examined by numerical methods. The transient impulsive flow over a flat plate is solved by a vortex sheet method and the particle transport equation is numerically integrated by the Strongly Implicit Procedure. The transient solutions are preliminary because refinement of the computer program is needed. Some trends and interesting features may be drawn from the results. Keywords Mathematical models Flow field Reynolds number.
