DISPLAY
This case concerns steady laminar flow near a rotating disk
in an infinite atmosphere.
The Reynolds number is sufficiently high for a self-similar
boundary layer to develop, as is shown by the facts that:
* the axial velocity w1,
* the dimensionless radial velocity v1/radius, and
* the dimensionless circumferential velocity u1/radius
* are all functions of axial distance alone.
Because the axial-direction grid spacing and the false-time-step
relaxation depend on the rotation speed omega, omega may be varied
over a wide range without other settings having to be changed.
