چکیده    We present a numerical study of the rotating flow generated by two rotating disks in co-/counterrotating, inside a fixed cylindrical enclosure similar to the czochralski configuration (cz). the enclosure having an aspect ratio a = h/rc equal to 2, filled with a low prandtl number fluid (pr = 0.011), which is submitted to a vertical temperature gradient. the finite volume method has been used to solve numerically the governing equations of the studied phenomenon.we present the steady state flow; and make a comparison between the flow generated by the co-/counter-rotating end disks. this study was caried out for different richardson numbers; ri = 0.01, 0.1, 0.5, 1, 2, 3, 5 and 10. the effect of orientation of the magnetic field is also taken into account for different values of the hartmann number (ha = 0, 5, 10, 20, 30 and 50). the obtained results show that the strongest stabilisation of the velocity field and heat transfer occurs when the flow generated byco-rotating end disks and the applied of magnetic field in radial direction provied a more stabilisation of the convective flow.
