Fluid-structure interactions of a cross parachute: numerical simulation

摘要

The dynamics of parachutes complex interaction between the parachute structure and the surrounding flow field. Accurate representation of parachute systems requires treatment of the problem as a fluid-structure interaction (FSI). In this paper we present the numerical simulations we performed for the purpose of comparison to a series of cross-parachute wind tunnel experiments. The FSI model consists of a 3-D fluid dynamics (FD) solver based on the Deforming-Spatial-Domain/Stabilized Space-Time (DSD/SST) procedure, a structural dynamics (SD) solver, and a method of coupling the two solvers.
