The objective of this research is to observe the effect endwalls have on the flow over an airfoil in a water tunnel. Analysis is achieved by attaching syringes to a pump that feeds dye through cavities inside of the airfoil, which then exits into the stream through small channels placed at various lengths along the suction side of the airfoil. The dye exits into the stream at a velocity such that its momentum allows the dye to take the shape of the flow over the airfoil – this velocity is calculated using jet in crossflow. Comparative analysis will be performed between the experimental results, and simulation from computational fluid dynamics. Expected results are vortex interactions such as horseshoe vortices over the airfoil at the endwalls, which break down towards the center of the airfoils span.
