Synopsis:

Numerical analysis of transport processes 2 introduces the most popular numerical methods for solving stationary and non-stationary heat and moisture transfer in porous media. It covers the finite difference method, finite volume method, boundary element method, and finite element method. The main attention is paid to the finite element method. The main principles are discussed, e.g., Galerkin's method, spatial and time discretization, various types of finite elements and approximation functions, and numerical integration. Students will practice simple benchmarks and computer implementation.

Study Objective:

Students will be able to apply their knowledge of the finite element method to practical problems of heat and moisture transfer. The output of the course is a short PC program based on the finite element method. This program will be used to simulate heat transfer throughout an external wall of a real building.
