title = "A direct discontinuous Galerkin method for computation of turbulent flows on hybrid grids",
abstract = "A Direct Discontinuous Galerkin (DDG) method is developed for solving the compressible Reynolds-averaged Navier-Stokes (RANS) equations with a modified Spalart-Allmaras (SA) model on hybrid grids. The characteristic face length in the numerical flux functions defined by the DDG method is carefully examined and re-evaluated to take into consideration the fact that grids in near-wall regions for high Reynolds number flows are generally curved and highly stretched. The effect with respect to the different choices of penalty parameter in simulating turbulent flows is also discussed in this work. A number of typical test cases are presented to demonstrate the performance of applying DDG method for high Reynolds number turbulent flows. Numerical results obtained demonstrate that the developed DDG method is able to deliver satisfactory and reliable results for simulating high Reynolds number turbulent flows and indicates its potential for practical engineering applications.",
