Investigation on the Theoretical Modeling of a Supersonic Flow CO Chemical Laser

抄録

Small signal gain coefficients of a supersonic flow CO chemical laser are calculated using a theoretical model which was developed previously and compared with the corresponding experimental results. It is shown that the model predicts the gain characteristics only qualitatively. The measured small signal gain coefficients are rather small compared with the calculated results. In the present investigation, the theoretical model is improved significantly by modifying the relaxation rate constants and by including the effects of the boundary layers which develop in the optical test section. However, further improvement on the theoretical model is necessary by including the effects of the nozzle boundary layers and shock waves.
