Insights from von Neumann analysis of high-order flux reconstruction schemes
High-order methods Flux reconstruction Nodal discontinuous Galerkin method
2015/7/3
Additionally, twodimensional non-linear numerical experiments are undertaken in order to assess whether results of the 1D von Neumann analysis (which is inherently linear) extend to real world problem...
An Analysis of Bodies Having Minimum Pressure Drag in Supersonic Flow: Exploring the Nonlinear Domain
Analysis Bodies Having Minimum Pressure Drag Supersonic Flow Exploring Nonlinear Domain
2015/7/2
One of the most interesting problems in supersonic aerodynamics has been to nd pro le shapes that have minimum pressure drag, subject to a set of geometric constraints. Considerable work was done in ...
