Preliminary Design of Low Speed Wind Tunnel

Abstract

This work demonstrates design procedure for low speed wind tunnel. Test section is the starting point for designing close loop wind tunnel, designing the other components depend on it. Such as settling chamber, two-dimension nozzle, two diffusers, settling chamber which contain honeycomb and series of screens, moreover corner vanes and axial fan. The design procedure contains the steps of calculating the pressure drop during these components, to be able to select a suitable axial fan. In addition to calculating the efficiency of the wind tunnel by the energy ratio.
