Experimental wake survey of low Reynolds number wind tunnel

Abstract

This poster presents the integration of a mechanical traverse and multi-hole probe for use in low Reynolds number wake surveys. Advanced testing equipment offers enhanced data processing and visualization of three-dimensional flow for wind tunnel wake surveys. The traverse and probe instrumentation can be used in many studies including research regarding advanced propeller designs for small unmanned aerial systems or upstream flow validation. This research project aims to integrate a traverse and multi-hole probe into existing LabVIEW framework in the ATRC 058 wind tunnel. The advantage to using LabVIEW rather than other data acquisition software is its intuitive visual interface and use of user inputs and automated controls. An Isel iMC-S8 controller and LES 5 linear actuator allow for full cross-sectional wake surveys while an Aeroprobe multi hole probe and air data computer stream angular flow data to the central computer. The integration of these systems allow for accurate real time measurements to be visualized and recorded directly into LabVIEW which can then be processed with MATLAB to provide informative data visualization.
