Credits: 6. Grading scale: TH. Cycle: A (Second Cycle). Main field: Technology. Language of instruction: The course will be given in English on demand. Optional for: F4, F4bem, M4bem, M4fo, Pi4. Course coordinator: Docent Johan Revstedt, forskarass Robert Szász, Johan.Revstedt@energy.lth.se, Energy Sciences. Prerequisites: MMV211 Fluid Mechanics, FMA430 Calculus in Several Variables, FMA420/421 Linear Algebra. Recommended prerequisits: MMVN01 Aerodynamics and Compressible Flow. Assessment: Examination is individual as well as based on group work. The compulsory home works and laboratory exercises are reported in writing, group-wise. No report is required from the computer exercises, however attendance is compulsory. The project assignment is reported both in writing and orally at a seminar, where all group members shall participate actively. The course ends with an individual written exam. To pass it is required that all compulsory parts, i.e. home works, project assignment and written exam are approved. The grade is based on the written exam. Further information: The course is based on lectures, exercises, computer exercises and group work in the form of home work and a smaller project assignment. Home page: http://www.energy.lth.se.

Aim
The aim of this course is to provide basic knowledge on modern computational methods which are commonly used for laminar and turbulent flows. Furthermore, the intention is to provide skills in the analysis and evaluation of results from numerical flow simulations. This knowledge should be sufficient to be able to chose an appropriate solution strategy and estimate the accuracy of the results for a given flow case.

Contents
The course contains methods for numerical solution of fluid mechanical problems, both compressible and incompressible. The system of governing equations can be predominantly hyperbolic, parabolic or elliptic depending on the character of the flow. The most common numerical solution methods for these types of systems of partial differential equations are treated. The course also discusses different typrs of discretisation (finite differences and finite volumes) and how these affect the accuracy and stability of the solution. Different types of computational grids and how these affect the accuracy are also treated. Furthermore, methods for increasing computational efficiency (multi-grid methods) are also discussed.
