Available in PDF, EPUB and Kindle. Book excerpt: This research program involves a computational study of the effects of disturbances generated from a moving particle on boundary layer transition. The practical importance of this problem stems from the fact that as an underwater vehicle moves through a particulate environment, particles enter the boundary layer and produce local disturbances. These disturbances may act as a bypass mechanism to transition and turbulence by interacting with boundary layer instabilities. The objective of this research is to study the basic mechanisms of the particle interaction and its effect on transition in the boundary layer. For this purpose, a direct numerical simulation is undertaken and the spherical particle is represented by a forcing function in the Navier Stokes equations. Results reveal good agreement with experimental studies. The report is presented in two parts. The first part concerns a general overview of the work accomplished and the second part summarizes our recent efforts on the modeling of steady/unsteady flow over a cylinder.
