A body-fitted structured grid approach to simulate breathing mode oscillations during parachute deployment

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.
