abstract
The presentation to be made is on the experimental study of a supersonic impinging microjet that was conducted to measure wall shear stress. 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. In contrast to a previous study, the plate temperature for this study was monitored vigilantly, and the camera calibration was carefully carried out in order to obtain more accurate wall shear stress results. The monitoring of temperature was especially important, as the variance of temperature affects the actual oil viscosity. Grids were used to calibrate the camera images before the analysis, in order to assure that the perspective of the lens did not affect the results. 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.
