Effect of wall electrical conductivity and transverse magnetic field on turbulent mercury flows in nonuniformly heated pipes
National Research University “Moscow Power Engineering Institute” (MPEI), Moscow, Russian Federation
The problem of mixed convection of mercury in a horizontal circular tube heated from below under the effect of a transverse magnetic field is examined. A numerical study was performed using the LES method in a conjugate formulation including the wall which may be with or without a fouling layer (deposits) with low electrical conductivity on its inner surface. To simulate the subgrid viscosity, the CSM model was used. In the case with a Reynolds numbers of Re0 = 5000, Hartmann number of Ha0 = 150, Grashof number of Gr0 = 2.75×106, which is based on the inner radius of the pipe, and Prandtl number of Pr = 0.024, a strong influence of the fouling layer electrical conductivity on the fluid flow structure and the amplitude and frequency of fluctuations of temperature, velocity, and electric potential has been found.
