Flow rate stream function
WebThe flow rate within the pipe is defined as the volume of fluid each second that is passing through a cross-sectional slice of the pipe, which is shown in the figure as a dotted circle. … The stream function is defined for incompressible (divergence-free) flows in two dimensions – as well as in three dimensions with axisymmetry. The flow velocity components can be expressed as the derivatives of the scalar stream function. The stream function can be used to plot streamlines, which represent … See more Definitions Lamb and Batchelor define the stream function $${\displaystyle \psi (x,y,t)}$$ for an incompressible flow velocity field $${\displaystyle (u(t),v(t))}$$ as follows.
