Abstract:A one-dimensional analysis has been performed on an induction wind tunnel, with a constant mixing section. Compressed air is injected into the back end of the tunnel by a simple converging-diverging nozzle; this induces a flow through the tunnel. The analysis is based on the conservation equations of mass, momentum and energy, where it is assumed the flow is isentropic throughout the tunnel and nozzle. The areas used in this report for the calculations are based on optimal area ratios investigated by Watanawanavet [6], and minimum required that are needed to fit test objects (fuselage panels). Some pointers and tips for setting up the Computational Fluid Dynamics (CFD) simulations are then given. Finally other ejector systems are recommended, which may have a positive influence on the performance of an induction tunnel. These can be used to test and optimize the injection system of the tunnel with CFD.
