Re-Design of a Wind Tunnel Outflow Section

Pier Giorgio Spazzini, Riccardo Malvano, Aline Piccato

Abstract

This paper deals with some of the problems connected with the design of a wind tunnel. In particular, the flow in the diffuser is analyzed in detail. The tool for this analysis was the numerical simulation, which allowed to forecast possible problems and to set up strategies to overcome them before the device was built. The simulations required to reach this aim will be presented, alongside with the results obtained. The results will be discussed in the light of the objectives of the device, which is designed to improve the performance of a reference test rig for airspeed measurement.
