Simulating a Quadcopter Propeller with CONVERGE 3.0
Autonomous meshing, high-fidelity turbulence models, and the efficient massive parallelization of CONVERGE 3.0 were leveraged to simulate a quadcopter propeller in this video courtesy of Dr. I-Han Liu and Dr. Roberto Torelli at Argonne National Laboratory. The first view shows a cut-plane of the vorticity distribution, colored by vorticity magnitude (blue indicates low; red indicated high).This simulation takes advantage of the Spalart-Allmaras turbulence model, new in CONVERGE 3.0. The second view shows the isosurface of the vortex structures for a propeller rotating at 5500 rpm, colored by vorticity magnitude. A Detached Eddy Simulation (DES) turbulence model was employed for this simulation. In both cases, Adaptive Mesh Refinement and fixed embedding were used to resolve the velocity near the blade, while also allowing for a domain large enough to capture the wake phenomena at a reasonable computational cost. With CONVERGE 3.0’s excellent parallel scaling, you can obtain accurate simulation results quickly, even for large cases. Convergent Science's CONVERGE is an innovative computational fluid dynamics (CFD) software that eliminates the grid generation bottleneck from the simulation process through autonomous meshing.
