Dear Friends,(adsbygoogle = window.adsbygoogle || []).push({});

I'm studying the 2D flows, and I have any questions.

In a square, there's a grid of flow in horizontal an vertical linear flow.

The flow that entry the square must be the same that exits form it.

[tex] \frac {\partial \Psi_e}{\partial x} -\frac {\partial \Psi_O}{\partial x}= \frac {\partial \Psi} {\partial x}= 0[/tex]

Becouse we have presure, we must apply navier-stokes'

[tex] \rho [ \frac {\partial {v_x}}{\partial t} + ( \vec{v_x} \frac {\partial}{ \partial x} ) \vec{v_x} ] = \mu \frac {\partial^2} {\partial x^2} \vec {v_x} - \frac {\partial p} {\partial x} [/tex]

How can I vinculate the presure with the flow in x and y directions?
