Introduction
Simulation of two-phase flows in pipes is one of the important topics in engineering sciences and various industries. Especially in the oil and gas, chemical and pharmaceutical industries. This type of simulation allows us to do this. to investigate the interaction and mixing of the two liquid and gas phases inside the pipes.
The particle dynamics model (DEM) is especially important in simulating the movement of particles in two-phase flows. This model allows us to observe the changes and interactions of the physical and dynamic details of the particles during the flow process. In mixing tubes, these interactions can have a significant effect on mixing efficiency and mass transfer.
In this research, an attempt is made to accurately analyze the two-phase flow in a mixing tube by using FLUENT simulation capabilities and DEM model. This parallelism between physical models and numerical simulations allows a deeper understanding of mixing and dispersion processes. And it can help to optimize industrial processes. Specifically, the aim of this study will be to investigate the effect of different parameters such as flow rate, pipe diameter and physical characteristics of phases on mixing efficiency.
Description
Simulation of two-phase flow and multiphase flows in Fluent are of increasing importance in the field of engineering. Two-phase flows are a subset of multi-phase flows and often include the simulation of a gas and a liquid. For example, the transformation of the liquid phase into the vapor phase in the pipe is an example of two-phase flows in the pipe. Considering that these flows are found abundantly in the industry, having expertise in simulating two-phase flows in Fluent is a requirement for many scientific and industrial activities.
In this project, Ansys Fluent software is used to simulate a mixing pipe using the two-phase DEM method.
