My channel having dimension 50 micrometer square cross section
My particle is of the size 25 micrometer diameter
The continuous fluid is water
the polystyrene bead having density 1060 kg/m3 is the dispersed phase
Inlet mass flow rate of water is 0.833e-6 kg/sec


My problem definition

With out any particle presence the flow through the square channel i simulated. i can find out the pressure drop on both ends of channel and this is simple simulation..then


sir i want to place one polystyrene bead at the inlet of channel..and i want to track the movement of bead.there is coupling of drag force of fluid on the particle and this particle can modify the flow field also.( two way coupling). No gravity effect.
finally at one position the the particle become steady by the two way coupling.I want to know that position..also i want to find out the extra resistance offered by this particle on the flow at this position..

thanks

help me please
