Experimental and Computational Investigation of a Gas Laser Pressure Recovery System Diffuser

Abstract

A diffuser, with the purpose of efficiently recovering pressure from a gas laser system, was designed and studied. A diffuser, as part of a pressure recovery system, is used in a gas laser system to transition the laser cavity's low pressure to the ambient pressure outside the device. The diffuser studied here is made up of constant-area supersonic section and a diverging subconic section. The diffuser is studied experimentally with pressure measurements and is modeled with 3-D CFD.
