Summary on Grant Application Form |
|
A six-week visit to NASA Langley is planned to work with Rumsey and Biedron. They have strong expertise in general and moving grid Computational Aero Elasticity (CAE) modelling. This has been stimulated by Boeing's sonic cruiser development work. (CASE, which brings together outstanding CFD (Computational Fluid Dynamics) researchers from around the world, is housed at NASA Langley. During the visit general moving grid and moving grid CAE techniques will be studied. Also, Tucker's previous DES (Detached Eddy Simulation) and differential equation wall distance work will be extended to timedependent geometry/grid problems. This previous research has the potential to give accuracy and efficiency gains. This is partly because, most practical CF predictions use turbulence models that need the surprisingly expensive to compute normal wall distance and temporal geometry changes can trigger separation. For time-dependent geometry changes, differential equation based wall distance approaches have better potential computational efficiencies tha search procedures. Also, they could actually improve accuracy and are highly compatible with DES (zonal LES) turbulence modelling techniques suggesting, new DES approaches. It is hoped to spend up to an additional week in the Mathematics Department at Berkley to work with Sethian, the originator of a fast Eikonal equation based distance approach that strongly relates to the above in a DES context.
