SIMULATION OF THE LASER DISCHARGE IN A SUPERSONIC GAS FLOW

Abstract

A heat model of the laser discharge in a supersonic turbulent gas flow has been developed. A numerical investigation of the error of the method of velocity measurements, which is based on the nitrogen molecules excitation, has been carried out. It is shown that fast gas heating by the discharge causes the velocity profiles deformation.
