Mixing properties of a viscoelastic fluid Part II: In a closed cylindrical cavity flow

Özet

Öz The laminar flow of Newtonian and non-Newtonian fluids with constant and variable shear-rate parameters are studied theoretically. Numerical Solutions for the concentration, partide path are obtained using fînite differences and A.D.I. method in 3D cylindrical cavity. Mixing properties are investigated by tracking the motion of a number of selected fluid particles and by simulating the dispersive mixing of a ‘coloured’ fluid injected into the cavity while at rest in both cylinder and concentric cylinder driven flow.
