Numerical Solution of Laminar Incompressible Boundary Layer Flow in Rotating Channels.

The equations of motion for two-dimensional laminar flow in rotating channels with divergent or parallel walls are simplified to the form of boundary layer equations and then solved numerically. The calculation yields the velocity and pressure distribution and their dependence upon parameters such as Reynolds numbers, rotation numbers and angle of divergence of the channel. The results show that the rotation decreases the pressure loss, which results from friction, in comparison with the stationary channel.
