“…A continuation method was employed to solve the flow field governed by the Navier‐Stokes equations in the free fluid, and Darcy equations in the porous region. analyzed the flow between a rotating and porous stationary disk, employing a combination of shooting and continuation methods to solve the flow problem. The effects of porous layer depth on the stresses and velocity profiles of the system were discussed in that paper.…”

The study of momentum and heat transfer has been carried out for the case of a viscous incompressible fluid between a rotating solid and a stationary permeable disk, whose depth is equal to that of the free fluid. Navier‐Stokes equations govern the flow in the free fluid, while the flow in the porous region is governed by a combination of Brinkman and Darcy equations, respectively. Energy equations in the free fluid region and the porous region have been considered. A two step numerical process is employed; series expansions are first created to give analytical approximations of momentum and energy equations in MAPLE, while a Runge‐Kutta algorithm bvp4c is then employed in MATLAB to numerically evaluate the velocity and temperature distributions in the flow fields. Velocity profiles, temperature profiles and relevant streamlines are sketched for various models involving variations in parameters such as Reynolds number, Brinkman number, and Prandtl number. It is observed that various parameters have differing effects on associated profiles which are subsequently discussed in the paper.

The experimental work presented in this paper relates to the local convective heat transfer on the rotor surface in the airgap of a discoidal rotor stator system. The stator used in these experiments is a multiperforated disk in which an air suction due to the rotation of the rotor comes through and enters the airgap. A thermal balance equation was used to identify the local convective heat transfer coefficient, with temperatures as boundary conditions, which have been measured by infrared thermography. The influence of the suctions is discussed for an interdisk dimensionless spacing interval G ranging from 0.01 to 0.16 and for Re between 129,000 and 516,000. Results are compared with precedent studies in which we obtained Nusselt numbers with a closed rotor stator system in which stator is a full disk and a rotor stator system with one hole at the stator center. It is shown that multiperforated stator can or cannot improve the rotor cooling, depending on G and Re.
