Abstract

A high fidelity multi-physics Eulerian computational framework is presented for the simulation of supersonic parachute inflation for landing on Mars. Several adaptive mesh refinement (AMR)-enabled, large edge simulation (LES)-based simulations of the full-size disk-gap-band (DGB) parachute inflating in the low-density low-pressure Martian atmosphere are reported. The comparison of the drag histories and the first peak forces between the simulation results and experimental data collected during NASA Curiosity Rover’s Mars atmospheric entry shows reasonable agreements. This framework demonstrates the potential of using Computational Fluid Dynamics (CFD) and Fluid-Structure Interaction (FSI) based simulation tools for the future supersonic parachute design. In the context of such multidisciplinary engineering design problems, I will also discuss potential challenges and endeavors undertaken with the aid of AI-based tools.
