Abstract:

For the requirement of application and design, the numerical simulation of the parachute is received more and more attention. As the most complex process, the computation model of the canopy inflation that couples CFD（Computational Fluid Dynamics）to MSD（Mass Spring Damper） is set up. The standard k-ε model is adopted in calculation the flow field. The flow-field of the parachute is simulated by the multiple block body-fitted grid generation method and the pressure field of canopy surface for the previous time step is imported to MSD code.
