Heat loss of buildings and proposals for measures to eliminate them
Dokoupil, Michael ; Škorpík, Jiří (referee) ; Baláš, Marek (advisor)
This bachelor thesis is dedicated to the issue of heat losses of the family house and thermal insulation design for their elimination. In the introduction, there is an overview of possible measures leading to the reduction of the energy consumption of buildings. Furthermore, the calculation of heat loss of a family house is described, generally and specifically, and thermal insulation variants are proposed to reduce heat losses. In conclusion, these variants are compared and the most economical solution is chosen.

A study of the vortex flow structures in heart compensation devices
Dokoupil, Michael ; Habán, Vladimír (referee) ; Fialová, Simona (advisor)
This master thesis is focused on study and description of flow in heart assistance devices. The aim was to evaluate the state of art for cardiac supports, selection of one device concept and improve the existing pump model. The types of heart replacements were evaluated in the research part of this work. Based on the research, an axial intraventricular pump was chosen for the simulation. The flow simulation was performed using computational fluid modeling. During the evaluation, special emphasis was placed on the description of vortex structures typical for cardiac support and analysis of hemolysis caused by the device.After selecting the optimization parameters, a design of a pump model was improved, which met the set optimization goals, especially the increase in efficiency and decrease of shear stresses. Towards the end of the work there was a discussion about the evaluation of hemolysis and vortex structures. In the end, particular possibilities for further improvement of the optimized pump were presented.
