Summary
The heat transfer of two-dimensional impinging air jets was examined. Jet widths from 0.0625 to 0.3750 inches (1.59 to 9.53 mm) operating at exit velocities from 2,000 to 10,000 ft/min (10.2 to 50.8 in/sec) were used. Average and local heat transfer coefficients were measured for jet arrays having a variety of different vertical and horizontal spacings. Predictive equations describing average heat transfer data were obtained which explain approximately 95 percent of the measured variation. Jet exit velocity and the lateral distance between the centerline of adjacent jets had the greatest influence on heat transfer.
