A GPU-Accelerated Mid-Fidelity Aerodynamic and Aeroacoustic Simulation Framework

A new solver based on the Vortex Lattice Method (VLM), 3D panel method and the Vortex Particle Method (VPM) has been presented that aims to provide a computationally efficient method to predict the aerodynamics and aeroacoustics of complex vehicle configurations. The solver uses just-in-time compilation techniques and GPU hardware acceleration to ensure time to solution is kept as small as possible. The solver was compared to experimental results for an isolated propeller and edgewise propeller, showing good agreement to experimental data. The aeroacoustic solver is based on Farassat's formulation 1A (F1A) of the Ffwocs Williams and Hawkings Equation, which has been implemented in the same framework as the aerodynamic part of the solver.
