Abstract :
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: C3H8 and CO2, 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 CO2 on the catalyst before emission in an atmosphere. The mathematical model includes an account of process of mixing and reaction of CO2 to C3H8, the mixture with air in the nozzle block, excitation in RF discharge, and processes of conversion CO molecules in CO2. 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 CO2 of the laser
