High-Order Adaptive Overset Mesh Methodology for Dynamic Ship/Aircraft Interface Simulations

Abstract

Develop and demonstrate techniques that increase the accuracy, efficiency and fidelity of dynamic ship/aircraft simulations for both fixed and rotary wing aircraft. Extend the capability of combined overset Discontinuous Galerkin (DG) off-body and near-body solvers to incorporate critical additional capabilities and physical effects and to enable accurate validated large-eddy simulations (LES) of wakes convected over large distances. Implement ship motion and atmospheric turbulence effects. Implement subgrid scale LES models into the off-body DG solver. Validate using a building block approach ranging from comparison with canonical turbulent flow problems to realistic ship airwake experiments. Study the effects of both h and p adaption strategies on overall simulation accuracy and efficiency. Establish the basis for future advances in simulation capabilities that will feed into the continued evolution of the CREATE-AV infrastructure while being directly applicable to NAVY specific aerodynamic problems.
