摘要: Mixing of two stratified miscible fluids in an eccentric stirred tank agitated by a four pitched-blade turbine was studied using the detached eddy simulation (DES) model and volume fluid (VOF) method. The were operated transitional mildly turbulent flow regimes. Interfaces between during mixing processes captured times computed. Effects Richardson number eccentricity on quantificationally analyzed. Results show that spatial temporal variations fractions can be well method presented this study. time increases with increase number. Effect depends agitation scheme is not advisable to use blend low-viscosity starting from state, especially for lower values.
