A High-Order CPR Method on Overset Adaptive Cartesian and Prismatic Meshes for Rotorcraft Flow Simulations

Abstract

This proposal is aimed at development and demonstration of the correction procedure via reconstruction (CPR) technique, a high order algorithm for overset adaptive Cartesian and strand prismatic meshes. Accuracy, stability, efficiency and robustness of the methodology will be investigated. The outcome of this effort will be an efficient and flexible computational fluid dynamics tool capable of high-fidelity prediction of flows relevant to rotorcraft vehicles. This proposal will develop the CPR formulation for a three-dimensional adaptive Cartesian mesh as well as for moving strand prismatic meshes. A robust interface treatment algorithm will be developed, allowing preservation of accuracy and reduced interpolation requirements (compared to current methods). Validation and verification studies will be performed to verify order of accuracy and demonstrate stability and robustness. The new developments proposed will improve current capabilities by providing increased accuracy for the near-body solver, enhancement of the high-order Cartesian solver, and more scalable treatments of overset mesh interfaces.
