Moving Finite Elements in 2-D -- Fluid Dynamics Applications.
Abstract
This report summarizes progress on the feasibility of using the moving finite element (MFE) method in two dimensional for the study of shock boundary layer interactions. It is found that highly local physical dissipation processes in regions of large gradients can be sensitive determinates of macroscopic flow properties. The MFE method continues to show promise for resolving such physical effects, while suppressing anomolous or numerical diffusion effects, over highly disparate physical scales. Recommendations are given for improving the MFE method for further reduction to practice for airblast applications. Keywords: Viscous Dissipation; Implicit Solutions; Partial Differential Equation; Navier Stokes Equations.
