Abstract

This research set out to manufacture a NACA-0012 airfoil capable of handling an array of Micro-Pillars to make large scale measurements of wall shear stress inside of a wind tunnel at low Reynolds numbers. The airfoil was constructed in two pieces using 3D printing and composite layups. The airfoil was smoothened with increasing levels of sandpaper grit and patched with Bondo to fill discrepancies in the carbon fiber composites. The airfoil was connected with cyanoacrylate glue and dowel pins. Once connected, a layer of paint was applied as a finishing touch. The airfoil contains a 0.25 inch deep slot, 1 inch wide, and 6.6 inches long, capable of holding a Micro-Pillar array to directly measure the velocity profile at the wall. This velocity profile can be utilized to determine the wall shear stress seen at each point of the Micro-Pillar array.
