Flow rate stream function
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. Given a point See more • Elementary flow See more • Joukowsky Transform Interactive WebApp See more WebVelocity (V) is related to volume flow rate (Q) (because Q = V*A) We can find out the flow direction by looking at the velocity direction of u and v. Direction of u and v ( Direction of V ( Direction of Q Solution Procedure: Step 1: Ensure that continuity equation is satisfied. Step 2: Solve for stream function (( or ( Step 3: Find the flow ...
