Abstract: The research was motivated by the ongoing the electromagnetic refining and continuous casting of molten metal. The calculation method of the fluctuation electromagnetic force in turbulent field of electroconductive was proposed. Together fluctuation electromagnetic force with the Navier-Stokes equation, the revised k-Ε model considering the effect of magnetic field application was derived. The specific model equations for the static magnetic field application were used to calculate the velocity distribution. The results show that the revised k-Ε model considering the effect of magnetic field application tends to suppress the production of turbulence, and time-averaged momentum become somewhat large. Calculated velocity difference between the conventional and revised k-Ε model is small.
