Influence of dynamic boundary conditions on the computed flow patterns inside a coaxial rotating disk-cylinder system

Abstract

In this paper, numerical solutions for the steady axisymmetric flow of an isothermal viscous fluid driven by moderate disk and/or cylinder coaxial rotation are presented. The influence of the two possible types of dynamic boundary conditions for the solid walls on the meridional flow features is discussed in detail using the computed Stokes streamfunction, angular momentum and vorticity distributions. Results show a clear dependence between the computed-generated flow patterns and the boundary conditions used. © 1991.
