Neutralizer with a gas ejector

Abstract

A neutralizer model with a gas ejector is studied, whose main element (a sonic nozzle) is a gap between two conical surfaces. Static pressure distributions were measured along the axis of the neutralizer at different gas pressures in the receiver. Stagnation pressure, total flow, gas target thickness, flow separation factor, Knudsen number, and gas-dynamic performance of the neutralizer were calculated from the gas pressure values on the axis of the neutralizer at the point with the coordinate z/d = 3, and static pressure distributions in the characteristic cross sections of the neutralizer were obtained. © 2012 Pleiades Publishing, Ltd.
