N2 - This paper presents a systematic numerical investigation of different Implicit Large-Eddy Simulations (ILES) for massively separated flows. Three numerical schemes, a third-order MUSCL scheme, a fifth-order MUSCL scheme and a ninth-order accurate WENO method, are tested in the context of separation from a gently curved surface. The case considered here is a simple wall-bounded flow that consists of a channel with hill-type curvature on the lower wall. The separation and reattachment locations, velocity and stress profiles are presented and compared against solutions from classical LES simulations.
