Ansys CFX Multiphase Flow Modeling

Course Overview

Multiphase flows often play a key role in industrial processes and understanding multiphase phenomena can be important for optimizing processes or products. Ansys CFX offers a range of models for multiphase flow simulation which can help you to understand multiphase flow phenomena in your application.



  • This course assumes that you have completed Ansys CFX Getting Started training and are already familiar with single phase flow in Ansys CFX.

Target Audience: 

Mechanical, Chemical, Aerospace, Process or Consulting Engineers or Engineers of any discipline who want to solve multiphase flow problems with Ansys CFX.

Teaching Method: 

Lectures and computer practical sessions to validate acquired knowledge.

Learning Pathway


Learning Outcome

Following completion of the course, you will be able to:

  • Describe basic concepts of multiphase flow theory such as phase definition and flow classification
  • Set up and solve problems using any of the multiphase flow models available in Ansys CFD software
  • Select the correct multiphase model for your Ansys CFD application
