摘要
In the present paper, numerical analysis of an electrically conducting fluid under the influence of a magnetic field in an inclined cylindrical annulus is presented. The inner and outer walls are kept at constant temperatures, and the top and bottom walls are assumed to be adiabatic. The numerical method used to solve the nonlinear governing equations of the problem is finite volume scheme. The computational results reveal that the effect of transverse magnetic field is more significant than that of the axial magnetic field on the average Nusselt number. Also, it is found that when the magnetic field is perpendicular to the axis of annulus, the average Nusselt number decreases from 7.8 to 4.7 with an increase in Ha from 0 to 60.
