High-order discontinuous Galerkin RANS solutions of the incompressible flow over a delta wing

The employed transition model is quite simplistic and the resulting simulation approach is not in general completely satisfactory, however the results accuracy establishes the major role of the turbulent transition in predicting the delta wing flow-field. Moreover our solutions fully confirm the interpretation of this flow given by Furman and Breitsamter (2006, 2008, 2009, 2013) [2], [3], [4], [5]. Finally, these computations put in evidence the robustness and the effectiveness of our high-order DG solver in dealing with large and complex problems on massively parallel architectures, using up to 4096 CPU cores.
