15 صفحه اولCfd Study of Mixing Process in Rushton Turbine
This paper reports on the CFD study of macro-mixing process of Rushton turbine in stirred tank. The code for mixing calculation is developed in the commercial CFD code CFX4.3. Mixing process simulation on different calculation method, different turbulent model and different tracer adding and detecting position are calculated. The simulation is three-dimensional and the impeller region is explic...
متن کاملComputational Flow Modelling of Dual Rushton Impeller Stirred Vessels
Flow in baffled stirred vessels involve interactions between flow around rotating impeller blades and stationary baffles. When more than one impeller is used, which is quite common in practice, the flow complexity is greatly increased, especially when there is an interaction between the multiple impellers. The extent of interaction depends on relative distances between the impellers and clearan...
متن کاملA Study on Liquid-liquid Mixing in a Stirred Tank with a 6-Blade Rushton Turbine
The turbulent flow field generated in a baffled stirred tank was computed by large eddy simulation (LED) and the flow field was developed using the Sliding Mesh (SM) approach. In this CFD study, mixing times and power number have been determined for a vessel agitated by a 6-blade Rushton turbine. The predicted results were compared with the published experimental data. The satisfactory results ...
متن کاملCFD Simulation of UV Disinfection Reactor for Applesauce with a Low UV Absorption Coefficient
In this study, a Computational Fluid Dynamics (CFD) model was developed to evaluate ultraviolet disinfection applesauce reactor. To simulate UV reactors, three sets of equations, including hydrodynamics, radiation and species mass conservation were solved simultaneously. The Realizable k-e turbulence model and the discrete ordinate method were used to find the UV radiation profile through the r...
