Turbocharger seals
Holík, Petr ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
This master’s thesis deals with theme of turbocharger seals. The aims of a thesis are to compare a turbocharger seals used in PBS Turbo turbochargers and to describe a testing of a seals. Principle of turbocharging and types of turbocharger are described in fist part. Next point of the thesis is describing of a face seals and non-contacting seals. The main part of the thesis describes kinds and reasons of seals testing; also contains comparison between labyrinth seals and piston ring, comparison of seals of PBS Turbo’s turbochargers and assesses the impact of turbocharger angle on the tightness of the seal.

Design of a hydrodynamic seal of an axial pump with an annular motor
Jančík, Kryštof ; Fialová, Simona (referee) ; Pochylý, František (advisor)
This diploma thesis deals with the design of a hydrodynamic seal of an axial pump with an annular motor, and it does so in three main thematic planes: research of current knowledge, simulation and experimental. The research section provides an overview of a broad problem of magnetic fluid seals (ferrohydrodynamic (FHD) seals), current developments in the field of simulation of internal flow in magnetic fluid and in the field of application of FHD technology in sealing liquids. It also covers a wider context of potential use for mechanical circulatory support systems that have had a significant impact on the proposed concept of a novel axial FHD seal. The remaining two thematic planes deal with his design and experimental testing.
