Hi

I have a channel of 50 micro x 50 micro x 1000 micro square channel.I am using VOF method to track the droplet movement.Secondary phase is water and primary phase is oil.The flow rate of oil is 50 micrlitre/min. I patch the secondary phase a sphere of diameter 25 micron inside the primary phase.How can i move the water droplet by the drag force of oil.I want to find out the change in pressure drop by the movement of this droplet inside the channel.

I am using transient simulation
Geo construct,explicit,first order upwind, pressure velocity coupled with volume fraction,Presto as the scheme

Even i did the simulation my droplet is not moving

My time period was 1e-7 with 3000 steps


Please help me\\\\\


Thanks
