Modification of a blood pump as a heart replacement
Simandl, Mirek ; Fialová, Simona (referee) ; Pochylý, František (advisor)
The master’s thesis deals optimization of regenerative pump and axial pump with ring motors that are designed as a heart replacement. Analysis of the koncepts is performed which were made in previous master’s thesis. There is created a new design of construction and hydraulition with using flat motors based on the analysis. The compact assembly of two impeller was formulated that replaced left and right heart and it served as a function of heart replacement. A functional model of the pump is created, there is measured characteristics of impeller and results are compared with CFD analysis. The design requirements some parts of the axial pump are added and it’s deviced feasibility analysis.

Identification of the contact angle anisotropy for hydrophobic surfaces
Simandl, Mirek ; Pochylý, František (referee) ; Fialová, Simona (advisor)
Bachelor thesis deals with the principle of solid/liquid interface. A water droplets behaviour is observed in contact with hydrophobic and superhydrophobic surfaces (contact angle exceeding 150°). The influence of the coating direction (unidirectional coating, perpendicular coating, both directions, uncoated and undefined) of the surface was evaluated. The contact angle anisotropy was examinedusing the SEE System software and its measuring accessories. Each sample was measured with three volumes of waterdroplet - 3l, 5 l and 10 l. Further, the influence of the structure on the droplet motion on an inclined plane was observed. Individual samples and groups with the same direction of the coating structure are evaluated. From these results are taken some general conclusions regarding to the influence of the direction of the structure and the droplet size on the contact angle anisotropy.
