Sumulation of Plasma Torche

The work is a study about main work features and properties of plasma of argon for designing and building plasma torches, to be employed in the projection of fine particles. The plasma properties in feature of their temperature and pressure are determinate and their behaviors inside the main element of the torche: the nozzle, is simulated. The influence of nozzles characteristics in the obtained plasma is determined, from finite elements models developed, being ended up defining the best nozzle parameters to be designed and built.
