MODELLING OF SLURRY HYDRODYNAMICS WITH TWO-BLADE IMPELLER IN TANK REACTOR

The paper presents computational fluid dynamics (CFD) method to hydrodynamics modelling of slurry in a tank reactor with a mixer. Numerical calculations were performed for two blade impeller. An analysis to obtain a uniform distribution of the solid particles in the whole volume of the slurry reactor has been carried out. Selected results of hydrodynamics simulation suspended solids catalyst CuO/ZnO in paraffin oil were presented respectively. These studies have been designed to determine the velocity and concentration fields of slurry in the reactor. Numerical calculations have been performed for a suspension of different diameter of particles, bulk density in the mixer without baffles. The lack of baffles had to limit the abrasion of solid particulates and improving the better mass transfer between the solid and the liquid phase.
