Summary on Grant Application Form
This proposal combines the expertise of two specialists: Dr. Wright, (CFD) and Profesor Knight (open channel flow). Key open channel flow and duct flow experimental data will be simulated and particular attention will be paid to the CFD output concerning isovels, division of flow between subareas, secondary currents, flow behaviour near the free surface and boundary shear stress distributions. Much of the experimental data will need to be re-analysed to obtain depth, lateral and sub-area averages in order to provide direct comparisons with detailed numerical and analytical results. Functional relationships for the lateral distributions of stress, depth mean velocity and turbulent mixing coefficients will be obtained. Different turbulence models will range from the non-linear k-epsilon model, giving some representation of anistropy, the k-omega model and a combined model (k-omega near the boundary and non-linear k-epsilon elsewhere). Further advances will be made on 2D analytical solutions to the depth averaged Navier-Stokes equations governing such problems. The aim of this proposal is to tackle the generic problem of open channel flow at a fundamental level, in such a way that it will lead to better simulations of complex flows which occur in practice.
