AN INVESTIGATION OF A JET IMPINGING ONTO A SLOTTED SURFACE

The Schwarz-Christoffel transformation in conjunction with the hodogra ph method is employed to determine the shapes of bounding streamlines for a two-dimensional air-jet impacting onto a slotted surface. In ord er to determine the solution to the problem, the Schwarz-Christoffel i ntegral is expressed in terms of mathematical functions in numerical f orm, from which the pivotal points in the half plane onto which the ho dograph plane is mapped, can be determined completely, enabling the ca lculation of the velocity potential and in turn the shape of the jet b oundaries.
