Learning outcome

The course gives an introduction to numerical simulation of heat transfer and fluid flow problems in industrial and natural processes. Emphasis is put on learning the practical use of numerical methods and to train their programming in Matlab and Fortran. The students will learn to assess the accuracy and to interpret the meaning of the numerical results in heat transfer and fluid flow.

Learning methods and activities

Lectures and lessons. Learning is based on extensive student activity in the form of solving exercise problems. The exercises include one larger exercise where the students develop their own program for solving heat and fluid flow problems. Programming in Matlab and Fortran. The teaching will be in English when students who do not speak Norwegian take the course. If the teaching is given in English the examination papers will be given in English only. Students are free to choose Norwegian or English for written assessments.
