Mathematical model of technological CO laser with 20-50 kW power, open contour of work and RF-discharge in supersonic flow

The mathematical model of a technological laser with an open work contour and RF-discharge has been developed in a supersonic flow. During the operating time of the CO laser there is a reaction on the catalyst of widely accessible gases: C/sub 3/H/sub 8/ and CO/sub 2/, with subsequent mix by air (up to 90%). The ecological safety of work of the laser is provided at the expense of CO conversion molecules in CO/sub 2/ on the catalyst before emission in an atmosphere. The mathematical model includes an account of process of mixing and reaction of CO/sub 2/ to C/sub 3/H/sub 8/, the mixture with air in the nozzle block, excitation in RF discharge, and processes of conversion CO molecules in CO/sub 2/. The model allows one to account for the parameters and optimisation of the technological laser and RF-discharge in a supersonic flow. The estimation of cost of such a technological laser with capacity of 20-50 kW is at a level of cost of a 1 kW CO/sub 2/ of the laser.
