The viscosity of adiponitrile waste liquid is as high 1000 cp. It challenging to spray and atomize the normally. Based on coaxial three-channel pneumatic atomizer, a two-stage supersonic steam atomizer proposed in this paper, atomization process simulated by Fluent software. Compared with traditional simulation method, Volume-of-Fluid Discrete-Phase-Model (VOF-DPM) bi-directional coupling model...

This paper presents the results of numerical simulations for developed and discussed conical two-phase atomizers with swirl flow, differing in ratio height chamber to its diameter. Experiments were carried out SAN-1 HS/DS = 1 SAN-2 4 atomizers. The study was conducted over a range Reynolds number liquid ReL (1400; 5650) gas ReG (2970; 9900). Numerical calculations performed use computational fl...

. A technique for hydrodynamic experiments has been developed to study a disk atomizer in rotary mass transfer apparatus. In the course of experiments, indicator method determines average residence time liquid on contact device, volume retained diameter droplets formed, and height gas-liquid layer

The effect of water droplets on strained methane-air laminar flames is investigated using particle image velocimetry both gas and liquid phases. We use the impinging flame configuration to measure speed (gas) as well motion phase, simultaneously. Water mean diameter 36.6 µm are produced by an ultrasonic atomizer dispersed in a methane/air flow, for constant molar ratio (12–36%) fuel (methane). ...

The article presents the developed mathematical models that describe process of spraying working body a low-volume sprayer. Theoretical studies show with an increase in supply fluid to atomizing disc, rotational speed pneumatic disc atomizer decreases, and order ensure effect air flow on droplet formation process, radius should be larger than base cone-shaped fairing, but less its maximum criti...
