Discontinuous High-Order Space-Time Methods for Moving Domain Simulation
Abstract
The proposed effort will develop a discontinuous Galerkin (DG) framework for unstructured moving grids. The PI will explore different numerical techniques that maintain accuracy in the simulation and wall clock efficiency. The proposed computational framework will be applied to a moving flap on a high-lift wing, and to wing in the wake of a moving L-shaped obstacle. The proposal describes numerical approaches to addressing the challenges of efficient solution strategies while maintaining consistency in the simulation during h (mesh refinement) and p (polynomial order) adaptations. A third year option will integrate a DDES strategy in to the framework. This option is essential to adding value to the proposed effort as the intent is to apply the framework to flows with large regions of flow separation. The approach here will be an S-A 1-eqn model for the eddy viscosity.
