Comparing grades axial steam turbines for various media
Staněk, Štěpán ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
Aim of the thesis is to design a single-stage axial steam turbine with impulse blading type for two different media with identical input parameters at input of stator and pressure behind the impeller. Calculation is made for water steam and organic fluid R134a. Main part of this thesis is termodynamic calculation and its optimalization in order to achieve maximum output and efficiency of the stage for both working fluids. At the end of the thesis an alternative calculation of impeller friction losses is presented.

Condensing Steam Turbine
Kracík, Petr ; Martinec, Jiří (referee) ; Fiedler, Jan (advisor)
Diploma thesis named Condensing steam turbine deals with heat scheme balancing computation of condensing steam turbine K55 and her design. This turbine with 5 unregulated take-offs and overpressure blading type, is computed with (c_a/u) method in the middle of blading diameter. Regulation degree is chosen with impulse blading and feet cross section is checked on durability. At the end of the thesis turbine consumption characteristic is derived from the zero output up to the nominal output. Integrated part of this thesis is conceptional design of longitudal turbine section.
