Simulation of Argon plasma torch for spectroscopic analysis (Ø 24 mm f=27.12 MHz, P=2 kW)

Computer simulation allows to choose the best torch design parameters rapidly and reduces the cost of experimental works.

Plasma temperature T, velocity v_z, v_r, v_f, pressure p, current density J_f , electric E_f and magnetic H_z , H_r field intensities, electromagnetic force F_z , F_r, power dissipation sE_f ² can be predicted for any torch geometry on a base of self consistent physical model.

Besides the plasma parameters the model can predict processed surface heating and powder motion, heating and melting inside and outside of the torch.
