N2 - A reconstructed discontinuous Galerkin method, namely RDG(P1P2), is presented for Implicit Large Eddy Simulation (ILES) of compressible turbulent ows on unstructured hexahedral grids. In this method, a least-squares reconstruction scheme is used to obtain a quadratic polynomial (P2) solution from the underlying linear (P1) discontinuous Galerkin (DG) solution in each cell for evaluating the uxes, which can significantly improve the accuracy of the underlying second-order DG(P1) method without much extra cost in computing time and storage requirement. The ILES performance by the developed solver is assessed through a series of lid driven cavity problems at high Reynolds numbers, where the turbulent ow features have been adequately resolved. The numerical results indicate that the RDG(P1P2) method is a promising candidate for the implicit large eddy simulation.
