Abstract

The effects of the supersonic nozzle shape on the performance of CO<SUB>2</SUB> gasdynamic laser are analyzed by solving time-averaged two-dimensional Navier-Stokes equations coupled with the vibrational relaxation equations for a CO<SUB>2</SUB> - N<SUB>2</SUB> system. The solver is based on a finite difference method with an implicit high accuracy TVD scheme. Numerical simulations are carried out for various types of supersonic nozzles. The performance is estimated with the indicator of the small signal gain coefficient. The results show possibility of improvement for small signal gain coefficient by nozzle shape modification and suggest a suitable nozzle shape.
