CFD (computational fluid dynamics) has become readily accessible and is widely applied in many aspects of the processing industries. A short introduction to CFD has been included in undergraduate Chemical Engineering courses with the aim of giving students an appreciation of its principal features. This comprised three lectures followed by practical experience of commercial CFD software applied to four simple fluid flow problems. A leading aim of the course has been to encourage a sceptical approach to initial results and to indicate methods by which their validity should be established.
