Title: Computing with Surface Roughness

Abstract: The importance of surface texture/roughness in the modeling of various physical processes involving heat transfer, diffusion, and flow, has been widely established experimentally. However, the precise variations in surface height are rarely directly observable. We discuss some statistical models that are commonly used to describe surface roughness and outline some methods to account for such statistical variations in numerical solutions of associated partial differential equations.
