Abstract
Flowing thermal plasmas are frequently used e . g. in welding, cutting, plasma deposition and testing materials at high temperatures . In most of the applications the geometry is complex . In the cascade arc the argon plasma flows through a straight circular channel with a constant area. The study of the flow and of the plasma properties are facilitated thereby.
Velocities in the order of 1000 m/s and mass flows of a few grams per second can be reached by applying a pressure difference of a few bar over the arc. The ohmic heating of the plasma also increases the flow speed. In this work a model is presented that shows the influence of the pressure, the ohmic heating and the thermodynamic properties of argon on the flow. Results of measurements will be given .
