Further Development and Application of High-Order Spectral Volume Methods for Compressible Flows

Autor: Carlos Breviglieri, Joao Luiz F. Azevedo

Publikováno v: Journal of Aerospace Technology and Management, Vol 9, Iss 3 (2017)

The present work investigates the high-order spectral finite volume (SFV) method with emphasis on applicability aspects for compressible flows. The intent is to improve the understanding and implementation of numerical techniques related to high-orde
