Transport phenomena associated with flow over a solid wavy surface
Abstract
Interactions between the flow and the wave result which occur when turbulent fluid flows over a small amplitude sinusoidal wave are examined. These interactions include fluctuations in the surface shear stress and pressure along the wave which have associated with them a phase and amplitude. Results of the analysis are used to support a linear stability mechanism for the formation of wave patterns in solid surfaces undergoing melting of dissolution. A variety of computational models for the solution of the appropriately linearized momentum equations were examined. The calculations of mass transfer rates to the wavy surface were also performed. It is shown that for certain values of the governing parameters the maxima in the transport rate can be located in the wave trough, and that it is possible to predict the selection of a wavelength which will predominate over others in the patterns formed on dissolving and melting surfaces.
