Computation of the two-dimensional flow over a hill and past a step by a ENO-type scheme

The computations of the flow over a hill (test case C-18 of the Ercoftac database) and past a backward facing step (test case C-30) are reported. The simulations were performed for all the grids supplied for the Workshop with two turbulence models, namely the one-equation model by Spalart and Allmaras (1994) and the two-equation k - ? model by Chang et al. (1995). The uncertainty was estimated by means of the least squares root approach (Eca and Hoekstra, 2002, 2003)
