Sensitivity of Gasdynamic Laser Calculations to Uncertainties in Kinetic Rates.

摘要

Recent data for the vibrational energy exchange rates associated with CO2-N2-H2O gas lasers is compared with previous compilatons. From this,current uncertainties in the rate data are established. Using an existing computer code, a study is made of the sensitivity of gasdynamic laser performance to these uncertainties. The results show that present-day calculations of gasdynamic laser gain and maximum available power are subject to at least a 25% inaccuracy due to such rate data uncertainties. (Author)
