| Abstract: | The dynamic behavior of parachute system is an extremely complex phenomenon.By applying the Computational Fluid Dynamics(CFD),the flow field of the parachute fully developed is computed based on the three dimension Navier-Stodes equations closed with S-A turbulence model.The simulation results are agreement with the experiment dates,which verifies that the accuracy of the numerical simulation model is ensured.The methods used in this paper can also be used in the design of other parachute systems. |
