Electro-osmosis flow does't re

I am doing simulate Electro-osmosis flow in COMSOL 4.3b, with Electrical Current, and Laminar Flow modules
BCs for Electrical current like:
Electrode: V0+sig_m*Z_DL*conj(Vy) with Z_DL = 1/(i*omega*C_DL), C_DL = eps_m*eplison0_const/lamdaD, lamdaD = 25[nm]
Symmetry boundary: 0
Other: Zero Charge
BCs for fluid:
Electroosmosis Velocity on Electrode
Open Boundary for Top boundary
Other: No slip
I am using Time Dependent study for both ( according to my attached file )
But actually, when I change frequency 30[MHz], the flow doesn't reverse.
Does anyone who familiar with EOF in COMSOL plz help me ?
Best regards
