Low speed wind tunnel design, setup. validation and testing of airfoils in turbulent inflow conditions

The present work aims to design and setup a low speed wind tunnel (LSWT) to be constructed at Mondragon Unibertsitatea for aerodynamic performance analysis of airfoils at low Re number. With this purpose, flow field characteristics through the test section are investigated to ensure that the flow qu...
