CFD simulation of refrigerant flow inside the semihermetic compressor
Tuhovčák, Ján ; Knotek, Stanislav (referee) ; Katolický, Jaroslav (advisor)
The CFD simulation of cooling piston compressor Stream, manufactured by Emerson company, is the topic of this diploma thesis. Analysis of moving parts (piston, valves) and refrigerant or physical settings for simulation were based on experimental data provided by Emerson. The goal of the thesis is to test opportunities of Star-CCM+ in simulating the flow inside the compressor. In the end there will be a comparison of experimental data and results from the simulation. The thesis also contains a theoretical background of piston compressors and phenomenon following the operating compressor.

The flow analysis inside semi-hermetic reciprocating compressor
Bouchal, Patrik ; Hejčík, Jiří (referee) ; Tuhovčák, Ján (advisor)
The topic of this diploma thesis is CFD simulation of flow inside CO2 semi-hermetic reciprocating compressor Stream manufactured by Emerson. The goal of this thesis is to analyze critical points inside the compressor with regard to excessive entrainment of oil by flowing refrigerant by means of CFD simulation using ANSYS CFX. Simulation for both single-phase and two-phase flow is part of the thesis and results from them are analysed.
