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 the trajectories of particles in a steady flow. The two-dimensional Lagrange strea… WebNov 3, 2024 · In this research work, we have obtained the stream function solution (in analytical form) of the Brinkman equation for parabolic cylindrical coordinates. …
