| This experimentation investigates the local heat transfer characteristics of an impinging jet with the effects of cross flow. The jet is formed by a single round hole with a diameter of 0.25 inches, sharp edges and a length to diameter ratio of 4. For one combination of impingement plate spacing and cross flow to jet flow mass velocity ratio, detailed photographs of a sheet of liquid crystal were taken. These photographs were then used to create a Nusselt number contour plot. Observations are made regarding the comparison of the Nusselt number contour plots with and without cross flow. Comparisons are also made to data in open literature citing the degradation of the average Nusselt number with cross flow to that without cross flow.;While the main focus of this study was the heat transfer of an impinging jet, a large amount of discharge coefficient data was also gathered for a single, sharp edged, round hole in the presence of cross flow. It compared very well to other investigator's data and a correlation relating the discharge coefficient to the mass velocity ratio is reported. |
