As the magnetic field Verteporfin applied in the X direction, the hydromagnetic drag acts along the Y and Z   directions, which decelerates the intensity of flow field in the respective directions. This is seen from the streamlines on the X=0.5X=0.5 plane of the cubic cavity. The flow is suppressed and the flow field becomes uniform with the increasing of Hartmann number, as shown in Fig. 4. The isotherm changes slightly ( Fig. 4(a) and (b)) when Hartmann number is varied from 0 to 50, when Hartmann number is up to 100, the isotherm changes considerably ( Fig. 4(c)).
On the Y=0.5Y=0.5 plane of the cubic cavity, trilobites is found that the thermal boundary layer thickness spreads into the center zone of the enclosure with Hartmann number, as shown in Fig. 5. It means that the distribution of the temperature become uniform gradually. The corresponding streamlines change remarkably.
