This thesis presents computational results on the flow through an element of the boundary-layer pump rotor in laminar and turbulent flow regimes, by which the rotor efficiency is predicted. The problem consists of source flow between co-rotating disks with parabolic flow assumption. Solution method of the parabolic Navier-Stokes equations includes Keller-box scheme and extended algebraic mixing-length turbulent model which reflects non-isotropic Reynolds stress due to disk rotation.
The results are presented with respect to the three parameters ; a rotational Reynolds number, a flow rate parameter and a gap spacing parameter. Discussion is made, from the point of applying the solution results to the development of a boundary-layer pump rotor.
