Hi all,

I was trying to simulate MHD for finding the velocity profile of flow in the gap under different magnetic field.

Dimension = length 40 mm height= 1.5mm

Magnetic field region = 5mm to 35 mm

Pressure inlet- 500pa
outlet - 0 pa

material - MR fluid

visco = 0.09 pas
permeability= 0.0008 H/m
Density= 3180 Kg/mm3.

i did simulation for 3T magnetic flux. But the velocity profile looks abnormal, velocity not reducing in the magnetic region, reduces only are the terminals of the field. Could any body please help me to find the profile.
