Grid topology for time-accurate deployment simulation of 2D Parachutes by using Navier-Stokes equations

Abstract

A new grid topology approach suitable for body-fitted structured grids is presented to time-accurately simulate deployment of parachutes. The goal is to provide an alternate to the current use of Cartesian and unstructured grids that are less desired from turbulence modeling aspects compared to the body-fitted structured grids. Time-accuracy essential for the deployment is maintained, unlike in the quasi-steady loose coupling methods used elsewhere with the Cartesian/unstructured grids. The current paper establishes the new approach for a 2D case that can lead to 3D cases.
