EFFECT OF PERMEATION THROUGH STATOR ON THE HYDRODYNAMICS OF A ROTATING DISK DYNAMIC FILTER

抄録

Fluid flow between a rotating disk and a stationary septum such as that in a rotating disk dynamic filter was studied theoretically and experimentally. The Navier-Stokes equations were solved in the laminar flow region of Re⟨10⁴ under reasonable fluid permeation rates through the stationary disk. The velocity profiles obtained by numerical calculation agree very well with the results determined by LDA measurement. Distributions of shear stress acting on the rotating disk and stationary septum are also presented in this study.
