Analysis Comparison between CFD and FEA of an Idealized Concept V-Hull Floor Configuration in Two Dimensions

Abstract

Several possibilities have been investigated that include studies with Courant number setting, Supersonic Static Pressure setting that shows Finite Volume and Finite Element results can be equivalent. The Effect of Mesh Density on Force prediction has been demonstrated. A 2-D type of analysis has been demonstrated to mimic that of a full 3-D analysis and are effective for what-if scenarios.
