Short course/CPD
Classical Turbulence Modelling
Course date: Please enquire
Course overview
The majority of natural and industrial flows are turbulent. Modelling turbulence accurately is usually critical as it usually determines fundamental properties such as drag, heat transfer, rates of chemical mixing and pressure losses. However, when simulating a turbulent flow there are many possible models which can be employed. The choice of model can affect the quality of the simulated results hugely.
Reynolds-Averaged Navier Stokes (RANS) methods are commonly used to simulate turbulent flows. This approach is ideal for industrial applications as the simulations are fast hence permitting rapid turn-around times. Despite their advantages, you must have a thorough appreciation of the pros and cons of each modelling approach otherwise there is a potential for large computational errors – especially for wall-bounded flows.
This course gives a detailed introduction to the fundamental turbulent flow physics and the application Reynolds-Averaged Navier Stokes (RANS) methods. It details the different modelling approaches from the most basic algebraic closures through to very complex Reynolds Stress Models. Each of these is discussed in terms of model complexity, accuracy and computational expense. In addition the problem of modelling flows close to walls is discussed.
It also includes hands on experience using RANS methods in the commercial software FLUENT.

Course description
Who should attend
This course is ideal for those who are:
- involved in the simulation of turbulent flows and need detailed best practice guidelines
- moving into the CFD of turbulent flows from another field
- larger businesses wishing to provide convenient and accessible continuing professional development to staff working in this field
- researchers/students who plan to or are currently studying turbulence and/or RANS methods
- experienced engineers looking for a refresher course on the physics of turbulent flows and current cutting-edge modelling techniques.
Benefits
Upon completion of the course you will be able to conduct an effective CFD simulation of a turbulent flow having:
- understood the underlying flow physics,
- made a trade-off between different applicable turbulence models,
- selected an appropriate grid resolution based on the flow physics and
- verified the simulation.
This will give immediate benefits to the sponsoring organisation as the returning employee/researcher will have a detailed understanding of turbulent flows. This means that he/she will be capable of critically evaluating the results of a turbulent simulation – an essential quality as turbulent flows are notoriously sensitive to modelling assumptions. This will lead to more accurate CFD solutions in a shorter time.
Topics
The course features lectures on an Introduction to Turbulent Flow Physics; Introduction to RANS Methods; Algebraic Closures; One- and Two- Equation Models; Higher-order closures; Reynolds Stress Models; and Wall modelling. There are hands-on sessions using RANS models in FLUENT.
