MRF polishing

In this paper we have design a model and it consists of two chambers with different dimensions, the chambers are
linked by a narrow channel and these two chambers are thermally contact with two temperature and channel
valves are thermally insulated. Using slip condition on the surfaces of valves in the vicinity of channels. The results
shows that in the steady state there is no net flow through the channel but the flow parallel to the walls in the
direction of thermal gradient develops due to thermal creep.
