A Pulsed Short Wavelength Chemical Laser (SWCL) is essentially a bomb that produces coherent light. Current leading candidates have exothermicities ranging from 68 to 248 kcal/mol. The challenge to the fluid dynamicist is to tame the explosion and produce a uniform optical media. Fluid dynamic analyses and experiments are essential to achieving scalable pulsed SWCL devices. We have originated designs of the three leading SWCL concepts with emphasis on the attendant fluid dynamics. With some additional analysis, we converted the device designs for use as flow simulators operating on the well known detonation of H2/02 which liberates 77 kcal/mol in the gas phase. In this paper we briefly present the analyses used to predict the pulsed SWCL flow behavior and discuss the conceptual designs of the flow simulators of the laboratory scale pulsed laser devices.
