please help me!
 
It is known that most solid surfaces obtain an instantaneous electrical charge when in contact with an ionic solution.For example, fused silica that is used commonly in the manufacturing of microchannels becomes negatively charged when it is in contact with an aqueous solution. Such a negatively charged surface will attract the positively charged ions (cations) of the solution. When an external electric field is applied on this system, the thin layer of cation-rich fluid adjacent to the solid surfaces will begin moving towards the cathode. This boundary layer-like motion will eventually set the bulk liquid into motion through viscous interaction. my question is how to simulate this process?thank you!
