Model of the Workflow of a Bladder Tank Diaphragm Foam Mixer and a Method for Calculating the Two Diaphragm Diameters

Chemical and Petroleum Engineering Aims and scope

The workflow of a bladder tank foam mixer is investigated. A physical and mathematical model of the workflow based on the Bernoulli and continuity equations with the use of empirical dependences of the hydraulic resistance and discharge coefficients on the Reynolds number is proposed. The resulting model allows determining the diameters of the dosing diaphragms in the first approximation. A numerical simulation of the workflow of a bladder tank foam mixer has been carried out in ANSYS CFX. A method for calculating the diameters of dosing diaphragms based on the physical and mathematical model and numerical simulation of the workflow using the method of successive approximation has been developed. An example of calculating the diaphragms of a foam mixer for a given range of water flow rate, foam concentration and diameters of the pipes supplying water and foam concentrate is given.
