چکیده
The hydrodynamics of stirred tanks and bubble breakup are crucial in gas-liquid flows, yet this system has not been well characterized for different operating conditions. In work, the numerical method was used to investigate six- flat blades impeller (Rushton turbine) results were employed understand behavior tank. Simulation predicted flow pattern, power number, distribution turbulence energy generated performed with COMSOL Multiphysics. Numerical showed good agreement experimental literature. effect rotational speed on behavior, such as breakage probability, average number daughter bubbles, time investigated using high-speed imaging method. main finding is that process occurs high area intensity, which located within a distance equal blade width radius (15-35 mm). probability (Bp) found be increased by 12.61 percent mother 4 mm at 340 rpm, an fragmentation up 22 fragments. Furthermore, decrease increasing speed, value 19.8 ms.

Numerical Comparison of Rushton Turbine and CD-6 Impeller in Non-Newtonian Fluid Stirred Tank
A computational fluid dynamics simulation is done for non-Newtonian fluid in a baffled stirred tank. The CMC solution is taken as non-Newtonian shear thinning fluid for simulation. The Reynolds Average Navier Stocks equation with steady state multi reference frame approach is used to simulate flow in the stirred tank. The turbulent flow field is modelled using realizable k-ε turbulence model. T...
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 کاملShear rate in stirred tank and bubble column bioreactors
Stirred tanks and bubble columns are widely used as mixing essels and bioreactors. Average spatial fluid velocity gradients t the level of the eddies or the prevailing shear rate, is an imporant variable in bioreactors but is not easy to characterize. A nowledge of shear rate is essential for at least two main reasons: 1) shear rate influences the average apparent viscosity of nonewtonian fluid...
متن کاملData on the mixing of non-Newtonian fluids by a Rushton turbine in a cylindrical tank
The paper focuses on the data collected from the mixing of shear thinning non-Newtonian fluids in a cylindrical tank by a Rushton turbine. The data presented are obtained by using Computational Fluid Dynamics (CFD) simulation of fluid flow field in the entire tank volume. The CFD validation data for this study is reported in the research article 'Numerical investigation of hydrodynamic behavior...
