Description

The objectives of this module are to provide a thorough description of the mathematical methods and numerical techniques used in Computational Fluid Dynamics (CFD) and to provide a practical experience in the use of a state of the art commercial modelling software. The module covers incompressible laminar and turbulent flow with heat transfer and involves both theoretical exercises and practical computational modelling of fluid and heat transfer problems.
