To develop and assess a lower-cost, higher-accuracy numerical simulation algorithm for unsteady jet aerodynamics and acoustic noise prediction using unstructured meshes.
Implemented a scale-resolving delayed detached-eddy simulation (DDES) framework using edge-based reconstruction schemes on unstructured computational grids.
Calculated far-field acoustic radiation using the Ffowcs-Williams and Hawkings formulation.
Benchmarked the algorithm using two test conditions: an unheated subsonic jet at Mach 0.9 and a sonic underexpanded hot jet.
Demonstrated accurate resolution of unsteady aerodynamic structures and far-field acoustic predictions with reduced computational resource demands.
Confirmed algorithmic efficiency across both subsonic and underexpanded sonic hot jet regimes.
