Abstract

The invention provides a numerical simulation method for the atomization of a suspension material to form a film, and obtains the relationship between the thickness of the liquid film and each parameter by means of dimension analysis and linear least square regression analysis. The liquid jet continuously impinges on the atomizing disk, the liquid jet spreads on the surface of the atomizing disk to form a film, the liquid film leaves the atomizing disk in a tangential direction, and breaks up to form ligaments or droplets. The computational fluid dynamics software FLUENT is used to numerically calculate the process, which avoids the high cost and waste of raw materials caused by experiments or blind design, and has certain guiding significance for the atomization mechanism of the feed liquid.

Description

technical field

[0001] The invention relates to a numerical simulation method for film formation on an atomizing disc of a suspension material. Background technique

[0002] Atomizing discs are widely used in the production of sprays, droplets, granules and powders. During the atomization process, a liquid film is formed on the disk, and the liquid film is broken into ligaments or droplets after leaving the edge of the disk. Atomizing discs are widely used in spray drying equipment, depending on the application of the method, these droplets produced can be solidified at high temperature to produce granules or powders, which can be obtained using this method of various sizes. The size of the droplets depends on the hydrodynamics of the liquid film formed on the disk and is directly related to the thickness of the liquid film.

[0003] Due to the complex atomization process of the material and liquid, it is extremely difficult to measure the thickness of the liquid film and ...
