Advanced 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.
Large Eddy Simulation (LES) becomes increasingly an established scientific computing approach for predicting transitional and turbulent flows. It is used extensively to elucidate the physics of turbulence and to compute flows of industrial relevance, wherever Reynolds-averaged models are not sufficiently accurate and direct numerical simulation techniques are prohibitively expensive. There are a number of different LES methods currently pursued by researchers, which share some similarities with respect to numerical and physical modelling, but also encompass advantages and shortcomings depending on the ‘design’ details.
This course gives a detailed introduction to unsteady turbulent flow physics, with a particular focus on DES and LES methods. It discusses the theoretical and numerical approaches, and the best practice to adopt when conducting an LES. Examples are given of LES of industrial problems demonstrating methods of analysis, verification and visualisation.

Course description
Who should attend
This course is ideal for those who are:
- involved in the simulation of complex turbulent flows and need detailed best practice guidelines
- 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 with a particular focus on unsteady flows.
Benefits
Upon completion of the course you will be able to conduct an effective CFD simulation of an unsteady turbulent flow having:
- understood the underlying flow physics,
- made a trade-off between different applicable LES models,
- selected an appropriate grid resolution based on the flow physics and
- verified and visualised the simulation.
This will give immediate benefits to the sponsoring organisation as the returning employee/researcher will have a detailed understanding of turbulent flows, and will know how to apply DES and LES methods to model unsteady turbulent phenomena. DES and LES methods have been clearly identified as the future for turbulence simulations, hence it is a key capability for any organisation using CFD.
Topics
The course features lectures on an Introduction to Unsteady Flow Physics; The Concept of Filtering; The LES and DES methods; LES Modelling approaches; Wall Modelling; Multiphase/Multi-species mixing; Analysis and Visualisation of Unsteady Flow Fields.
