Abstract
An ejector for pumping a low pressure, supersonic driven stream to a high pressure is disclosed. Effective pressure recovery in a relatively short axial length is sought. The low pressure driven stream is flowed at supersonic velocities into the ejector. A high energy driving stream is flowed laterally of the driven stream at a supersonic velocity greater than the supersonic velocity of the driven stream and a static pressure above the static pressure of the driven stream to cause compression of the driven stream at supersonic velocities.
