Numerická simulace procesu termosanace stavebních konstrukcí
Kučera, Martin
This bachelor's thesis deals with the numeric simulation of hot-air treatment of wooden elements of roof truss constructions. The thesis is divided into two main parts. In the first, theoretical part, analyses of an air-flow in the area of treated construction and a heat transfer from a pre-heated air to the wooden construction are elaborated. Necessary theoretical background - laws of convection and heat transfer are listed. The second part of this thesis consists of simulations of hot-air wood treatment in particular applications. Appropriate 2D and 3D models of given situations were created and used as inputs for the finite element method analyses. Gained results are graphical depiction of the velocity of air-flow surrounding the treated elements, temperature distribution in their surrounding and cross-section of the elements itself. In order to derive the required time of the treatment process, temperatures in appropriately chosen points have been measured.
