摘要
A numerical simulation method for parachute Fluid-Structure Interaction (FSI) problem using Semi-Implicit Method for Pressure-Linked Equations (SIMPLE) algorithm is proposed. This method could be used in both coupling computation of parachute FSI and flow field analysis. Both flat circular parachute and conical parachute are modeled and simulated by this new method. Flow field characteristics at various angles of attack are further simulated for the conical parachute model. Comparison with the space-time FSI technique shows that this method also provides similar and reasonable results.
