Eulerian Multiphase Model Training Course

Description

Eulerian Multiphase Model Training Course

The Eulerian multiphase model is a numerical simulation tool to model the behavior of multiple phases in a system. It is based on the Eulerian approach, which tracks the motion of each phase separately.

The model can be used to simulate a wide range of multiphase flows, including bubbly, dispersed, and droplet flows. It can also be used to simulate the interaction between different phases, such as the drag force between two phases, and the heat transfer between them.

The model can predict the system’s behavior under different conditions, such as pressure, temperature, and flow rate. There are various CFD methods to employ this model. One of the most renowned methods is the Finite volume method available in ANSYS Fluent.

ANSYS Fluent is a powerful tool that can simulate Eulerian-based multiphase flows. The implemented options and existing capabilities of this software can predict even the slightest alteration of phases when interacting with each other.

Training Course Syllabus

This course contains video lessons and final projects to get a certificate after finishing the course.

Lesson 1: Eulerian Multiphase Model Concepts

In this lesson, you will first see a general introduction to the Eulerian Multiphase model and an overview of available simulation techniques and sub-models of the Eulerian in ANSYS Fluent. This section contains the following subsections:

• Eulerian model applications & applicability
• Regime transition modeling
• AIAD submodel
• GENTOP submodel
• Boiling model
• Interfacial area concentration VS. Algebraic interfacial area
• Applicable forces
• Turbulent interaction & models
• Euler-Granular model
• Summary

Lesson 2: Unconfined Pool Boiling

In this lesson, we present a practical example for you. We will examine the boiling phenomenon in a 2D cylinder (axisymmetric rectangle) and try to observe the generated vapor’s motion.

You will see how to enable the basic RPI boiling model and how to set up a proper boiling simulation by enabling the mandatory forces and their respective models. We will also show you some tips on how to obtain correct numerical results from this simulation as the boiling simulations are generally a bit tricky to handle.

Lesson 3: Fluidized Bed Bio-Reactor

In this lesson, we present a different example from the previous example. In this session, we will investigate the granular material behavior inside a bio-reactor. We will show you how to set up the proper conditions for granular matter. Also, you will be familiar with each of the available settings and models for granular flow.

Lesson 4: Carbonate Cake Filtration

In this lesson, we will delve deeper into the simulation of the granular flow by providing an example of packed bed flows. Packed bed flows are fixed regions of solid matter. What you will see here is how the packed bed region, simulated through a granular flow model, can filter another normal granular flow.

This type of application is named as cake filtration process in the industry, where a layer of solid (accumulated particles) accrues on the filter (packed bed region).
