| Abstract: | The role of electromagnetic forces and the forces of viscous friction with the arc plasma flow in the flow formation within
the cathode melt is considered within the framework of numerical modelling; a comparative estimation of the separate influence
of each of the above forces is carried out. The melt flow pattern is found to form mainly by electromagnetic forces. The character
of the effect of electromagnetic forces is determined to a considerable extent by the ratio of the radius of cathode attachment
of the arc on the melt droplet and the rod cathode radius. |
