Computational and Experimental Study of Oil-water Emulsion Flow and Stability in a Stirred Tank
Oil-water emulsion flow behaviour was characterized with respect to surface chemistry. A state of the art stirred tank experimental set up was constructed that measured dynamic droplet size evolution with varying impeller speed. This technique was demonstrated with model Nexbase oil (with and without SPAN 80 surfactants) and water emulsions. Further, a CFD model for droplet size prediction was ...
متن کاملCoagulation in a Continuously Stirred Tank Reactor
Smoluchowski 's coagulation equation with coagulation rates K 0 oc (ij) ~ describing the temporal evaluation of the size distribution ck (concentration of k-mers) is studied in the presence of a source term ark, and a sink term --bCk. With a' a/b 2 one finds that a steady state is reached, exhibiting gelation when w > 1⁄2 and a ' > ao(w), where a0(o~) depends on w (ao(w) = ~ for ~o < 1⁄2, ao(1)...
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 کاملLarge Eddy Simulation of Stirred Tank Flows
Impeller stirred tanks (STR) are commonly used in the chemical processing industries (CPI) for a variety of mixing and blending technologies. In the present research, a numerical study of flow and mixing inside turbulently agitated tanks were carried out. An efficient solution algorithm was developed to solve turbulent flow inside stirred tanks where the boundary conditions for moving impeller ...
