“…Computations with the complete tunnel geometry but with a simplified plenum of reduced size have been conducted in the HiReTT EU project [5]. Although there exist computational results, there are no properly validated results yet, as the slot wall flow is very complex and dominated by unsteady phenomena, separations, boundary layer effects, and secondary flow effects [6]. Thus, an unstructured Navier -Stokes grid properly representing the complete slot geometry and a plenum can be expected to have well beyond 10, probably exceeding 20 million nodes.…”

This article presents a simplified computational fluid dynamics (CFD) model of the European Transonic Windtunnel test section that represents the model support in a far field and is specifically designed for the investigation of model support effects in the transonic regime. Two parametric studies were carried out in order to determine geometric parameters of the adapted support geometry and in order to enable the simulation of actual wind tunnel experiments, by correlating the wind tunnel reference Mach number with that at the far field in the CFD computation and the effective Mach number at the model location. A comparison was done using measured calibration data from the wind tunnel.
