description: A bibliographic observation was conducted, due to which the method based on description of magnetohydrodynamics (MHD) plasma was adopted for electric arc modeling. The generated system of equations makes it possible to create a computer model of an open AC arc with changing geometrical parameters in the COMSOL MultiphysicsÂ® software. The verification of the developed arc computer model in COMSOL Multiphysics (KMD-CM) was carried out. It has shown good qualitative and quantitative agreement between calculated and previously published in different sources results. Created KMD-CM allows to calculate temperature distribution within the channel, as well as the current, arc electric field and radius oscillograms in industrial frequency networks depending on thermodynamic properties of plasma, design and parameters of the external circuit.
