Webb11 apr. 2024 · It is therefore important to first establish close agreement in the pressure distribution close to the bend between the simulation and the experiment. Note that in the current case without flow separation, the pressure distribution is determined largely by the wall geometry and the inviscid effect, presumably unaffected by the wall-modelling details.
