Sensitivity Analysis and Validation of a Computational Framework for Supersonic Parachute Inflation Dynamics

What is it about?

This paper tackles the challenging task of simulating supersonic parachute inflation dynamics (PID). These fluid-structure interaction (FSI) simulations involve capturing heterogeneous flow features at different scales such as shocks, under-expanded jets, turbulent wakes, and thin boundary layers. These complex flow features interact with a highly nonlinear porous woven fabric canopy and thin braided suspension lines, which can be computationally expensive and challenging to model. The research focuses on establishing sensitivity of the simulation accuracy to different modeling and simulation choices. This was done thoroughly by designing an array of simulations with varying levels of fidelity.
