Problem 2 A stream function in a two-dimensional flow is y = 2xy. Show that the … WebQuestion: A stream function for a given flow is given by (where U and L are positive contants with dimensions of m/s and m, respectively): psi(x,y) = U/L_2 (3x^y-y^3). State … asus router login url 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 … 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.
