Numerical calculation of the temperature distribution in hot burning plasma

الملخص EN

The influence of the laser beam focusing condition on the efficiency of the localized interaction with the gas indicated and the method proposed for increasing this efficiency in the presence of hot burning plasma are studied.

The intensity distribution of the laser radiation in the focal plane and in the adjacent region of the laser beam is determined.

Our calculations depended on the solution of two-dimensional Navier-Stokes equations together with paraxial ray equation ; ionisation equation and the energy equation.

A finite differences Algorithm employed to solve these equations.

The active area divided into 3321 non-uniform mesh.

All calculation depends on the real gas properties including the absorption coefficient.

Some results will be present in this paper.
