Fluidic Jet Impingement—Analytical Solution and Novel Physical Characteristic


THE chief obstacle to the solution of liquid jet problems is the fact that free surface locations are not known a priori. So total force at an impingement surface can be related to gross flow quantities, but pressure and velocity variations in the impingement zone are not deducible theoretically. Inspection of the integral equations expressing the standard conservation conditions of fluid mechanics has furnished, by an inductive argument, an acceptable asymptotic formula for splash thickness resulting from oblique impingement of a circular jet on a flat surface. A novel physical feature is the occurrence of a dry zone when the impingement angle is less than π/3.
