A Study of the Effect of Random Input Motion on Low Reynolds Number Flows.
Abstract
The SwRI large water tunnel was modified by the addition of a large test section (.71 m x .81 m x 1.8 m long) to provide low Reynolds number flows with low blockage for models in a highly separated flow condition. Flow characteristics are documented and other physical features are described. The feasibility of conducting water tunnel experiments involving unsteady aero-hydrodynamics was demonstrated by performing a series of flow visualization studies on a oscillating airfoil (NACA 0012). This experiment was carried out at a reduced fully separated until 17 degress angle of attack, and the downstream wash of the separated flow occurred at 22 degrees. (mjm)
