摘要

•Discontinuous Galerkin and Petrov Galerkin methods are investigated and developed for laminar and turbulent flows.•Curved surface mesh is generated using a CAPRI mesh parameterization tool for higher-order surface representations.•Interior mesh is deformed via a linear elasticity strategy to obtain valid high-order finite element meshes.•Accuracy is assessed between the discontinuous Galerkin and Petrov Galerkin discretization methods.
