Development of a Mixer Design Using Numerical Methods to Calculate Flow Hydrodynamics in the Working Volume

Abstract

The influence of the location of inlet nozzles for a secondary liquid stream on the flow structure in the working volume of ejection mixers used to produce water-in-oil emulsions was studied using numerical methods. The parameters and physical properties of a working medium corresponding to those of process oil supplied to industrial electrical desalting plants were calculated using the SST k –ω turbulence model. The ergonomics of the developed apparatuses could be preliminarily evaluated by using numerical methods to analyze the distribution of velocity and pressure fields in the working volume. An even number of inlet pipes for the secondary reagent that were located opposite each other improved the mixing conditions in the mixers and used the energy of the primary stream to produce turbulence and disperse secondary-reagent streams.
