Abstract:

	The purpose of this project is to develop an accurate and highly efficient parallel
algorithm based on asynchronous, multilevel, adaptive methods for computational fluid
dynamic problems involving transition caused by canonical roughness elements. Boundary
layer transition is extremely sensitive to the presence and nature of roughness elements,
but very little in known either experimentally or numerically about the precise nature
of this relationship. The ultimate goal of this project is to develop effective computational
tools for numerical analysis of these physical processes. The Phase I project will
develop a prototype method for two-dimensional and three-dimensional, steady, incompressible
flow in a channel. The approach will involve the development of the asynchronous,
fast, adaptive, composite-grid method for such problems on the INTEL iPSC/2 using
several different roughness elements, hemisphere, sphere, and cylinder.

Potential Commercial Application:

Potential Commercial Applications: This project should enable parallel computer simulation
of steady-state and time-dependent simulation of three-dimensional flows in transition
involving canonical roughness elements.
