Contents

In the introductory part an overview of various numerical solution methods is presented and the governing equations are classified. The finite volume and the finite difference techniques are mainly considered. The applicability and limitations of the methods are described. The treatment of convection-diffusion terms is extensive. Numerical diffusion is discussed in details. Algorithms for the pressure-velocity coupling (e.g., SIMPLE, SIMPLEC, SIMPLEX, PISO, etc) are presented. Staggered and non-staggered grids are explained and turbulence modelling is introduced briefly. Methods for solution of algebraic equations are presented. In the design tasks (assignments) the students will perform calculations with pocket calculators, write their own computer codes and apply a more general-purpose computer software. By solving a number of tutorial problems the skills for numerical soloution of heat transfer problems are strengthened. Experience on application to real heat transfer problems is established.

Examination details

Grading scale: TH
Assessment: After every study period (quarter) a written exam takes place. Thus two written exams are included. An exam has generally both theoretical questions and problems to be solved. The exam after the first study period (lp 1, quarter 1) encompasses 40 % theory and 60 % problem solving. The exam after the second study period (lp2) is mainly problem solving. Each exam has 50p (points). As the theoretical questions are solved closed books prevail while for the problem solving part the course material except solved problems is permitted. For the problem solving part also the textbook in the Heat Transfer course is permitted. The exam thus needs to be splitted which means that at first the theoretical questions are solved and as these have been handed in to the exam assistant, the problem solving part can be started. In the second study period (lp2, quarter 2) some lectures will be given by representatives from some industries. The application of commercially available computer codes (so-called CFD codes) for solving flow and heat transfer problems will be presented. In addition lectures concerning, e.g., complex geometries, special problems etc. will also be given. Some of the PhD students in Heat Transfer will show how CFD methods are encountered in research projects.
