THE FLOW-INDUCED BY A ROTATING-DISK IN A PARTICULATE SUSPENSION

A typical finite volume fraction two phase flow model is used to inves tigate the influence of assumptions about the nature of particle phase viscosity and the structure of particle phase boundary conditions at a solid surface on solutions to the Von Karman problem for a particle/ fluid suspension. Solutions are obtained numerically by an iterative f inite difference method. Comparisons of these solutions with one anoth er and with previously published work reveal that both the particle ph ase viscosity and solid surface boundary conditions influence the natu re of predictions in important ways. Selected numerical results are pr esented graphically to illustrate these conclusions.
