Possibilities for replication of spraying nozzles by means of 3D printing methods
Petrenec, Jan ; Malý, Milan (referee) ; Jedelský, Jan (advisor)
This bachelor thesis deals with the possibilities of using additive manufacturing (AM) in case of replication of pressure swirl atomizers in order to reduce the financial costs as well as the production times achieved by the existing production processes. Several goals were set by an assignment of this thesis. In particular, the individual 3D printing methods were discussed in detail and the specific selected type of spray nozzle was introduced, together with their requirements that have been elaborated in detail. The applicability of the individual representatives of AM was also evaluated, and their comparison was made. The result of this work are two potentially useful methods for replicating pressure swirl nozzles, namely Micro Laser Sintering and Direct Metal Laser Sintering. Due to lack of time and the already large extent of this thesis, an optional 6th task was not carried out and the experimental verification of these set conclusions remains a question for further studies.

Accumulation of electricity for a source with unstable production
Petrenec, Jan ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with possibilities of accumulation of electricity generated by renewable sources with unstable production. Several goals were set by an assignment of this thesis. Within a research, current trends of the accumulation are presented in detail on examples of specific representatives with their technical parameters and economic possibilities. Further, an unstable source of electricity – the wind farm of three power plants Multibrid 5000 with all its parameters and operational details is defined for purposes of individual designs of accumulation systems. Firstly, the detailed design of an advanced compressed air energy storage (A-CAES) is realized. It includes a thermodynamic calculation of chosen components, their partial technical solutions, a financial evaluation of investment and a determination of theoretical payback period. Furthermore, the design for accumulators Tesla Powerpack is realized. It contains a calculation of individual system parameters, a financial evaluation of investment and a determination of theoretical payback period. Last part of the thesis is dedicated to a comparison and an evaluation of the achieved results of both realized methods of the electricity accumulation. In the end, A-CAES is chosen as more perspective variation.
