Method for the solution of conduction heat transfer in Phase change material with nanoparticles
Kopečková, Barbora ; Knotek, Stanislav (referee) ; Jícha, Miroslav (advisor)
This master thesis deals with problematic of the heat convection in phase change materials (PCM) and PCM with nanoparticles. The derivation of stationary and non-stationary equations for 1D, 2D and 3D heat convection are described in detail. The finite element volume method is used for solution to these equations, of which principle is described carefully. The aim of this thesis is model development for 2D solution to temperature distribution at heat convection in PCM and influence assessment of nanoparticle implementation into material on given temperature distribution. Software MATLAB was used for model development, solution and plotting graphs.

New external thermal insulation composite system taking in to account the sustainable use of natural resources
Sokola, Lubomír ; Rovnaníková, Pavla (referee) ; Vejmelková,, Eva (referee) ; Nosek,, Karel (referee) ; Žižková, Nikol (advisor)
The work is focused on the development of an environmentally friendly external thermal insulation composite system in terms of product composition and composition of the whole system. The intention is to develop an alternative to standard external thermal insulation composite systems. Undoubtely, standard systems have a contribution to energy savings (primary role), but their actual production and composition is also a burden on the environment. The research is focused onthe development of adhesive and leveling substance and plaster using progressive material with phase transformation and energy by-product (fly ash). Furthermore, it is focused on the selection of insulation from renewable sources. Therefore, there is paid attention to the overall composition of the thermal insulation system in order to achieve the most effective impact with respect to the environment. The goal is to achieve secondary energy and resource savings due to the composition of components and also the composition of the entire system.
