Investigation of Transient Flow and Heating Problems Characteristics of High Energy Laser Gas Circulation Systems.

Abstract

Complementing the Army effort on the Closed Cycle Circulator for repetitively pulsed electric discharge lasers, a project was conducted to develop computer programs modeling the recirculating gas flows in pulsed laser operation including steady and unsteady cases; to perform theoretical analysis of the unstable resonator with tilted spherical mirrors; to conduct an experimental investigation of transient fluid and thermal characteristics of the recirculating flow associated with the pulsed laser operation using a subscale circulator; and to experimentally determine the effects of mufflers, screen packs, and honeycombs on acoustic and thermal waves propagated in the recirculating flow.
