Abstract

A unique experimental cascade aerodynamics test facility has been developed at Wichita State University (WSU). The established facility utilizes the WSU 3.5 feet × 6 feet (1.07 m × 1.83 m) water table and hydrogen bubble flow visualization technique. A high-resolution CCD (Charge Coupled Device) video camera captures images of the visualized flow, and the image data is then processed by an image processing computer program utilizing MATLAB® standard toolbox software package. A series of validation tests have been conducted in this facility, and results from these validation tests indicate that the facility is capable of quantitatively measuring the velocity field information. The established test facility is currently being used to measure the detailed velocity field of a NACA 65- series axial compressor cascade model in order to determine the energy loss in terms of entropy generation rate for low Reynolds number applications. This paper includes preliminary test results from blade surface boundary layer measurements of a NACA 65(12)10 three-blade rectilinear cascade model with 20-inch-chord length.
