This type of flow would be prevail flow inside channels of
DPZTFFC device and we must discuss it first.
Equation (3) with the boundary conditions u=0 for y=+/-b
describe steady flow in channel between two parallel plates.
And solution for this case is parabola.
Another simple solution of equation (3) is obtained for
so-called Couette flow between two parallel flat walls, one of which is a rest
the another moving in its own plane with constant velocity.
We will investigate another application for equation (3) - the
flow near oscillating flat plate - the Stokes's second
