Description
The United States Army is seeking to develop high-fidelity, computationally efficient solvers for aerodynamic analysis and design of vehicles including rotary-wing aircraft and hypersonic projectiles. The project aims to improve prediction of aerothermodynamics, including boundary layer transition, turbulent heat fluxes, and vortex dynamics at high Reynolds numbers. Phase I involves assessing current solver capabilities against benchmark experiments and conducting uncertainty analysis. Subsequent phases include modifying solver codes and integrating the tools into Long-Range Precision Fires applications.
