Heat transfer coefficient on surfaces of steam turbines
Belko, Milan ; Pavel, Pánek (referee) ; Pospíšil, Jiří (advisor)
This thesis in introductory part aims to analyze the available literature on the heat transfer coefficient in labyrinth seals and rotating discs of steam turbines. The available experiment studies were processed to summarize heat transfer coefficients on the rotating parts of the turbine. Then, this thesis specifies a design calculation to determine the heat transfer coefficient in selected parts of the turbine, exercisable for specific geometric and operating parameters. The outcome of this work is simulation of rotor dilation of operating steam turbine in the program Ansys during cold start of turbine.
Measurement of COP-temperature relationship of air-water heat pump
Belko, Milan ; Hejčík, Jiří (referee) ; Jaroš, Michal (advisor)
This thesis bachelor’s deals with the measurement of heat pump operation the air-water unconventional construction, which is installed in a family house. Furthermore, evaluating and comparing the measured data with a heat pump air-water standard of construction and subsequent assessment of the economic benefits of building their own specific heat pump.
