Steam Turbine Revision
Potměšil, Tomáš ; Novotný, Zdeněk (referee) ; Fiedler, Jan (advisor)
This work deals with current application of the developing field of post-warranty service of old turbines in the energy sector. There are described various types of repairs following the recommendations of commonly performed actions. Revision finding is focused on back-pressure steam turbine marked R12-9 / 2, which was scheduled for overhaul after 180 000 operating hours. Revision findings include a detailed description of the turbine and method of repair. It is also performed calculating the losses in the axial blade stage of cascade by AMDC-KO methodology on because of the choice type of blading and then comparing by technical justification for the choice of one of the variants for the customer.
Flow characteristics measurement of intake and exhaust ports on SF 260 flowbench
Školař, Karel ; Ramík, Pavel (referee) ; Beran, Martin (advisor)
This Bachelor’s thesis deals with experimental modifications in order to increase the filling efficiency of the combustion engine. The thesis contains a search for issues dealing with increasing the filling efficiency of the engine. To verify the modifications on the cylinder head, measurements were performed in the laboratory at the flow bench. At the end, the measured results were compared and evaluated.
Experimental determination of flow characteristics the intake and exhaust ports of cylinder head
Mecerod, Vít ; Svída, David (referee) ; Beran, Martin (advisor)
This bachelor thesis is focused on research of flow characteristics of cylinder head ports and its measurements using flow benches. Special focus is being placed on formation of discharge coefficient as it is one of the major outputs of said measurements. Usage of coefficients is than discussed as they are widely used for calibration of 1D simulations.
