摘要：

A two-dimensional two-phase fluiddynamic model with included k - epsilon(diss) turbulence model was used to calculate local values of velocity, holdup and effective viscosity of both phases. The simulated results are compared with experimental ones. The influences of drag coefficient, radial forces and the modelling of the effective viscosity are discussed.
