Sometimes the stream function is defined such that it bears a specific physical relationship to the volumetric flow rate for example, if you have flow in a tube, the stream function can be taken to be zero at the centerline, and equal quantitatively to the axial volumetric flow rate between the centerline and an arbitrary stream surface at .

You have free access to this content a stream function approach to optical flow with applications to fluid transport dynamics. In the stream-function formulation the pressure is eliminated via the incompressibility condition, however occasionally it is useful to examine it in order to gain some insight to be clear, this pressure is an auxiliary field, and the accuracy of the simulation isn't dependent on it. Stream function stream function is a very useful device in the study of fluid dynamics and was arrived at by the french mathematician joseph louis lagrange in 1781 of course, it is related to the streamlines of flow, a relationship which we will bring out later.
