Aim

The aim of this course is to provide basic knowledge on modern computational methods which are commonly used for laminar and turbulent flows. The most common turbulence models and their effect on the numerical solution are also discussed. 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. A discussion on the most common turbulence models based on the Reynolds averaged Navier-Stokes equations (RANS) and how these can affect the numerical solution is also included.

Examination details

Grading scale: TH
Assessment: Examination is individual as well as based on group work. The compulsory home assignments and laboratory exercises are reported in writing, individually. No report is required from the computer exercises, however attendance is compulsory. The project assignment is reported group-wise both in writing and orally at a seminar, where all group members shall participate actively. The examination also includes a test on the theoretical content of the course. To pass it is required that all compulsory parts, i.e. home works, project assignment and the test are approved. The grade is based on the home works, project assignment.
