Steady flow of a jet of fluid from an angled slot impacting on a horizontal wall

The flow of a jet of liquid emanating from an elevated, angled slot and impacting on a horizontal wall is considered. An exact solution for high flow speeds is computed, and a numerical technique is used to compute solutions for a range of slot widths, entry angles and separation heights as the flow rate decreases. It is shown that for a given height and slot width there is a minimum flow rate beneath which no steady solutions exist. The cause of this minimum flow is the formation of a stagnation point at the upper exit from the slot, but the height is also a factor in determining the flow rate at which this occurs. The proportion of outflow to the left and right along the horizontal surface for different flow rates and angles is computed.
