Potential flow, control volume, and frozen vorticity models have been used to analyze the wall jet-receiver system. The potential flow model predicts well the extent of the region of influence upstream of the receiver entrance for jet widths the same order as the receiver width, but the assumption of irrotationality drastically mispredicts the receiver spill flow angle. A control volume model which accounts for the extent of influence upstream of the receiver entrance and the possibility of continuous wall stall accurately predicts the receiver spill flow angle for most receiver spill flow ratios. The frozen vorticity model predicts velocity profiles in the receiver entrance region reasonably well, and slightly overpredicts the pressure recovery coefficient in the receiver entrance region.
