A bstract : The present study is the second half of a two part work carried out in collaboration with SNECMA which tends to investigate a shaped hole film cooling experimentally and numerically. The aim of this paper is the numerical study of 3D phenomena induced by cylindrical and shaped hole film cooling on a flat wall. The two calculations show up classical structures such as horseshoe or kidney vortices and their differences according to the shape configuration. A detailed study demonstrates their influence on the jet behaviour. Comparing both cases reveals the impact of shaping on the velocity field and vortex motions. The calculations were performed by resolving the 3D Navier‐Stokes equations associated with a k‐ε turbulence model. The solver is the CANARI code developed by ONERA.
