NUMERICAL ANALYSIS OF THERMAL PLASMA FLOW IN A PIPE.

Thermal plasma flow in a water-cooled pipe was investigated using numerical calculations for three models for the physico-chemical state in the piop pipe: thermal equilibrium, a frozen state, and an approximately real state. The velocity and energy fields are different from ordinary pipe flow and vary characteristically depending on the state in the pipe and the initial conditions. The velocity along the center line of the pipe increases initially and then decreases, while the mixed-mean temperature and the mixed-mean total enthalpy decrease somewhat differently.
