Flow Field Analysis and Verification of Microbubble Generator Based on Three-Phase Flow Dynamics

Abstract

In this paper, the three-phase flow dynamics model is established. These models, including the Euler multiphase flow model and the discrete phase model, are applied to analyze the flow field of the microbubble generator numerically. Considering the interaction between three phases and the action of the intraphase, in the Euler–Lagrangian coordinate system, the gas phase is the discrete phase to analyze the mutual coupling of gas and liquid phase. In order to study the effect of the homogeneous addition on the gas-liquid two-phase flow, solid particles are considered as pseudo-homogeneous, introduced into Euler coordinate system and establish a two-fluid model. Based on the numerical simulation of the flow field of the microbubble generator, different parameters are set for analysis to verify the rationality of the mathematical model and provide reference for the experimental verification and structural optimization design of the microbubble generator.
