Anotace:

The course is focused on numerical modelling of heat and water vapor transfer in building constructions and buildings. The solution of various types of diffusion and convective-diffusion equations (e.g. heat transfer by convection and conduction and the combination of such transport mechanisms) is being discussed with emphasis on the possibilities of the finite element method. Main part of the course deals with practical applications of CFD (computational fluid dynamics) modelling for the solution of selected building physics problems (e.g. air, heat and moisture transport in spaces with different usage and heat sources, the influence of leakages in constructions on the moisture transfer and the risk of vapor condensation, hygro-thermal behaviour of constructions with ventilated air layers etc.). Students will have opportunity to work with several software simulation tools during the course so they will be able to study discussed transport phenomenons practically on specific examples.
