Abstract
The present version of the PRUV code (Plume Radiation of Ultra-Violet) utilizes flowfield input from the JANNAF SPF2 code and computes plume ultra-violet spectral signatures resulting from the emissions of CO-0 chemiluminescence, aluminum oxide, zirconium oxide or carbon particulates, and the individual lines of four molecular band systems. Collision and Doppler effects are computed for each molecular line for use in absorption calculations. Spectral signatures were computed for two missiles, herein named Missile A and Missile B. The Missile A plume contains aluminum oxide particulates while those of Missile B are composed of zirconium oxide. Temperature dependent imaginary refractive index (n ) values of zirconium oxide were estimated through use of the phenomenological Urbach Tail Model. Agreement with measured results for both missiles was generally within a factor of two. Such agreement is considered good for this stage of development of the code. A brief description of the present stage of development of the PRUV code is given.
