abstract
This presentation is about the continued experimental study of wall shear stress caused by the impingement of a supersonic impinging microjet on a plate. The method of oil film interferometry was used to measure the shear stress. Measurements were made for various height to diameter nozzle ratios and nozzle pressure ratios as well as several different oil viscosities. The plate temperature for this study was monitored vigilantly. In order to obtain accurate wall shear stress results, a camera calibration was run for each different set of tests and grids were used for camera image calibration to account for camera perspective. Monitoring the temperature was especially important, as the variance of temperature affects the actual oil viscosity. Unlike the previous semesters of this study, final tests were run this time, and the temperature data was actually used in the analysis. The results of the study indicate that wall shear stress rapidly decreases as the distance from the impingement point increases. The study of wall shear stress created by microjets is important due to its present use in clean rooms and for spot cooling, more specifically the cooling of parts on small parts and electronics. note
