EXPERIMENTAL INVESTIGATION OF THE VISCOUS EFFECTS ON BALANCED JETS IN GROUND PROXIMITY

Abstract

An experimental investigation was made of the flow field beneath a two-dimensional ground effect machine and in the vicinity of its peripheral jet for various nozzle heights. The shape and location of impingement on the ground of the dividing streamline were determined, measurements of the approximate size and shape of the base vortex were made along with vorticity and velocity measurements, and measurements of pressures along the base of the machine were made. All of these experimental results are compared with the theory presented in a previous report.
