Study on the foam production characteristics of air self-suction foam generator by jet by Caiyuan Lu, Yuxin Wu, Di Zhu, Yuntao Liang

“…For this reason, this paper analyzes the foaming characteristics and forming principle of air self-suction foam generator, and simulates and studies the over-current ratio of rectifying orifice plate with the help of Fluent software, $$\varphi$$ (the ratio of the area of the fluid that can pass through the rectifier disk to the vertical cross-sectional area of the fluid flow), the distribution patterns of flow field, pressure, and turbulence intensity inside the foaming machine are determined by the nozzle cavity spacing and mixing cavity diameter. The study demonstrates that water flow is the most effective means of entraining air, and that the contact between the fluid and foam network is most thorough when the overflow ratio of the fan disc ( $$\varphi$$ ) is 0.455, the distance between nozzle cavities $$\mu$$ (the distance between the nozzle and the closest end face of the foam chamber vertically.) is 200 mm, and the diameter of the mixing chamber ( $${d}$$ ) is 260 mm. …”
