AC electroosmosis problems (weak form)

Please login with a confirmed email address before reporting spam

Hello guys,

I want to rebuild N.G. Green's AC electroosmosis model
(journals.aps.org/pre/abstract/10.1103/PhysRevE.66.026305)

I have some difficulties in deriving Navier-stokes equation in weak form:


Here are what I typed in the "weak" term in COMSOL:

eta*(test(ux)*ux+test(uy)*uy)-(px+py)*test(u)

I don't know how to deal with the pressure terms in the equation,
Need some advice, thanks.
