Ansys Fluent
Combustion Modeling

Course Overview

This course is designed for existing users of Ansys Fluent. You will learn and achieve an understanding of the basic theory of the models for reacting flow applications, advantages and disadvantages of each model. The knowledge gained will enable you to select the most appropriate modelling approaches for your target applications and simulation objectives.

The advanced combustion modelling course has several tutorials that the students can work through in their own time after the lectures.


  • A technical education and background in fluid mechanics and heat transfer is recommended but not mandatory. An engineering degree is not required.
  • Completion of the Introduction to Ansys Fluent course is required.
  • Experience with Ansys Fluent is strongly recommended.

Target Audience

Engineers and Designers

Teaching Method

Lectures and computer practical sessions to validate acquired knowledge. A training certificate is provided to all attendees who complete the course.

Learning Path


Learning Outcome

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

  • Categorize reacting flows in terms of flame type (premixed, non-premixed, partially premixed) and chemistry type (finite rate chemistry, fast chemistry) and choose the correct combustion model for your problem based on this categorization
  • Set up and perform simulations involving simplified finite rate chemistry using the finite rate/eddy dissipation model and how to set up and perform simulations involving detailed finite rate chemistry
  • Set up mixtures of reacting species and define material properties for finite rate chemistry simulations
  • Define chemical reactions in Fluent and how to import Chemkin reaction mechanisms
  • Set up and perform simulations involving detailed finite rate chemistry and how to employ chemistry acceleration tools such as ISAT, chemistry agglomeration, dynamic mechanism reduction and dimension reduction
  • Set up and perform simulations involving surface reactions on walls and in porous media
  • Set up and perform simulations of non-premixed, premixed and partially premixed reacting flow systems
  • Define and compute PDF tables and laminar flamelets for non-premixed and partially premixed calculations
  • Select appropriate combustion models for use in large eddy simulations (LES)
  • Use the discrete phase model (DPM) to set up and perform simulations with combustion of liquid fuel droplets or solid fuel particles
  • Set up and use models for pollutants such as NOx, SOx and soot
  • Identify radiation models in Fluent which can be used with combustion simulation and choose the correct model for a given application
