Abstract

A new grid topology approach suitable for body-fitted structured grids is presented to time-accurately simulate the deployment of parachutes from start. The goal is to provide an alternative efficient body-fitted structured grids to Cartesian/unstructured grids for more accurate modeling of turbulent flows. Time-accuracy essential for deployment is maintained, unlike in the quasi-steady loose coupling methods used elsewhere with Cartesian/unstructured grids. Prediction of breathing mode during deployment is demonstrated. The current paper establishes a new approach for accurately simulating deployments from the start.

模拟降落伞展开过程中呼吸模式振荡的人体拟合结构网格方法

本文提出了一种适用于人体拟合结构网格的新网格拓扑方法，用于在时间上精确地模拟降落伞的起始部署。其目的是为笛卡尔/非结构网格提供另一种高效的体贴合结构网格，以更精确地模拟湍流。与其他使用笛卡尔/非结构网格的准稳定松散耦合方法不同，该方法保持了部署所必需的时间精度。本文演示了部署过程中的呼吸模式预测。本文确立了一种从一开始就精确模拟部署的新方法。
