Processing and analysis of HS videorecords of liquid atomization for a pressure-swirl nozzle
Červenec, Adam ; Lízal, František (referee) ; Jedelský, Jan (advisor)
This bachelor thesis deals with processes of liquid atomization for a pressure-swirl nozzle. The main goal was to study liquid cone, which is gradually fragmenting on smaller parts ending in creating small droplets. It was needed to study theory of liquid flow, motion of droplets and an impact of the geometry of nozzle. When the theoretical part ended we could perform an experiment, which consists of preparing devices and creating own video records using highspeed camera Photron FASTCAM SA-Z. The camera provided us detailed view on the spray and events, for example collisions of droplets, which are the main subject of this thesis. Afterwards the video records were analyzed and we could provide results connected with studied problem.

Steam Turbine for Compressor Drive
Červenec, Adam ; Fiedler, Jan (referee) ; Kracík, Petr (advisor)
The purpose of the diploma thesis is the design of condensing steam turbine for driving a compressor with mechanical power of 14,5 MW and operating speed 6800 rotations per minute on the compressor clutch. The main part is the thermodynamic calculation of the blade canal, which is verified with strength calculation to meet the requirements of the standart API 612. The next part is a basic design of gland sealing system, including a piston which is leveling the axial force with reusage of steam back to the blade canal. This thesis includes a calculation of axial and radial forces including the choice of suitable bearing, which both support the turbine. In the end there is an operating characteristics and function reliability of rising rotating speed on the total stress of blades.
