This course provides core knowledge of the fundamentals of CFD for engineers, and an introduction to the methods and analysis techniques used in CFD. It also provides an introduction to the use of commercial CFD codes to analyse flow and heat transfer in problems of practical engineering interest. The emphasis of the course is on the use of CFD as a virtual fluid laboratory. By studying a variety of flow situations students will develop a better intuition of fluid mechanics more quickly than is possible with traditional analytical approaches. At the end of the course you will understand the process of developing a geometrical model of the flow, applying appropriate boundary conditions, specifying solution parameters, and visualizing and analysing the results. This course will give a proper background for using commercial CFD packages
