Optimization of the Liquid Mixing Process in a Vertical Capacitative Apparatus with Mechanical Mixing Devices

The problem statement for optimizing the design parameters and operating mode of mechanical mixing devices of vertical capacitive devices is presented, the optimality criterion for the solution of which is the total length of the velocity vector of the mixed medium. A mathematical model is developed of the mechanical mixing process using the Reynolds-averaged Navier–Stokes equations closed by the turbulence equations. The adequacy of the model is confirmed by experimental studies. A method for optimizing the design parameters and operating mode of mechanical mixing devices is proposed, which provides for the justification of the selection of the selected values of the design parameters and operating mode. The methodology is implemented in a problem-oriented system for optimizing the design parameters and operating mode of mechanical mixing devices, implemented in the design and engineering department of PAO Pigment (Tambov).
