mathematical modeling of iDEP

Hello Dear Alisha

I am trying to model iDEP via comsol. I have used creeping flow and electric current modules in a stationary solver to model electroosmotic flow in an insulator based DEP micro device. My runs seem fine but it is inconsistent with the values in a paper that I am trying to model.
The fluid velocity in the channel is 1.4 mm/s (about 5 mm/s between adjacent vertical posts) but the velocity of fluid in the paper is about 5um/s.
I want to ask you what ranges of values for velocity was obtained from your calculations?
Is x mm/s rational for an iDEP?
Model details: channel dimensions(10mm* 1mm*10um)
Including 8*4 circular posts
Posts configuration: 200 um in diameter and 250 um center to center distance
Voltage applied to the device: 800 on right side and 0 on the other side of the 1 cm long channel.
I have assumed zeta potential of 16 mV at all the surfaces of the channel including posts surface and Micro channel walls.

Please help me through this.
