Cfd Analysis of Turbulence Effect on Reaction in Stirred Tank Reactors
نویسنده
چکیده
Stirred tank reactors are one of the most commonly used equipments in industry for achieving mixing and reaction. Flow fields in a stirred reactor are obtained via computational fluid dynamics. In this work CFD is used for the simulation of a reactive flow process consisting of a second order reaction. The extent of reaction is found to depend on impeller speed and its position from the bottom of the reactor and therefore on the mixing behavior during the steady state process. The flow field based simulations performed led to predictions that are very well compared with the experimental data. These results are obtained by modeling through finite volume method using FLUENT (version 5.5). Impeller induced boundary conditions are important aspects that significantly enriches the mathematical representation of the primary source of motion in tanks. The results are compared with experimental values obtained from a laboratory stainless steel reactor employed with marine impeller.
