Toplotna analiza zaščitenih lesenih elementov : diplomska naloga

Špiler, Jan (author), Hozjan, Tomaž (mentor)

V diplomski nalogi je predstavljena in prikazana uporaba numeričnih metod za modeliranje prenosa toplote po zaščitenih lesenih gradbenih elementih izpostavljenim požaru. Za namen diplomske naloge je bil, v programskem okolju Matlab, izdelan numerični model na podlagi metode končnih elementov z uporabo trikotnih končnih elementov. S pomočjo predstavljenega numeričnega modela so bile med drugim izvedene analize vpliva toplotne izolacije in vpliva vlage v lesu na potek ogrevanja lesenega elementa. Ugotovljeno je bilo, da ima tako toplotna izolacija kot vpliv vlage velik vpliv na razpored temperature po lesenem elementu.

• Title: Heat transfer analysis of protected timber elements

Abstract

This thesis presents and demonstrates the use of numerical methods in heat transfer modeling for protected timber elements exposed to fire. A numerical model based on finite element method with the use of triangular finite elements has been produced in the software environment Matlab, solely for the purpose of this thesis. The presented numerical model helped conducting analyses on the impact of thermal isolation and the impact of moisture in timber on the development of the heating regime in a timber element. The results show that both thermal isolation and moisture in timber have great impact on temperature distribution in timber element.
