降落伞工作过程数值模拟研究综述

Review on the Development of Numerical Simulations on Parachutes

回顾了降落伞研究方法从实验方法、半经验半理论方法到仿真模拟方法的发展历程,显示了数值模拟方法在降落伞研究方面的巨大前景。同时总结了伞衣流场数值模拟、伞衣结构数值模拟、流场和结构耦合的数值模拟的最新进展,通过研究发现,降落伞流固耦合数值模拟研究的主要方法是任意拉格朗日欧拉方法(ALE)、变空间域/稳定时间-空间(DSD/SST)方法和浸没边界法(IBM),这些方法代表了降落伞流固耦合技术研究的最新水平。

The development history of parachute research methods from experimental methods, semi empirical and semi theoretical methods to simulation methods were reviewed, which shows the great prospect of numerical simulation in parachute research. The developments of Computational Fluid Dynamics （CFD） simulation of the fluid field surrounding the canopy, Computational Structure Dynamics （CSD） simulation of canopy structure and Fluid Structure Interaction （FSI） simulation of canopy structure were introduced, which mainly use ALE method, DSD/SST method and IBM method. These methods represent the latest technique level of the research on the parachute fluid- structure interaction.
