An analytical and experimental investigation on -pressure distri¬bution about wedges was initiated because, of some problems encountered in transporation cooling;the results obtained are of general inter¬est and application. The analytical investigation of incompressible flow about finite wedges showed that decreasing the tunnel-wedge ratio (the tunnel-wedge ratio is defined as ratio of tunnel height to maximum wedge thickness) decreased the pressure coefficient at all chordwise locations;an increase in wedge angle with an unbounded stream (infinite tunnel-wedge ratio) caused a pressure coefficient increase in the forward region and decrease in the rear region of the wedge. It was also found that, even for a wedge in an unbounded stream the region of applicability of the infinite wedge-type velocity distri¬bution assumed in the solution of laminar boundary layer equations is "approximated only within 10 percent for a limited leading-edge region. Additional calculations indicated that use of- a theoretical instead of an experimental pressure distribution should be satisfactory for heat-transfer predictions for regions not unduly influenced by flow separ¬ation.
