Diplomová práce se zaměřuje na jednodimenzionální studium dynamického chování ventilu pístového kompresoru. Za tímto účelem byl vytvořen program, pomocí nějž jsou kvalitativně hodnoceny jednotlivé projevy dynamického chování a jejich vzájemný vliv. Matematický model, jenž je v tomto programu implementován, je v práci rovněž detailně popsán.
Annotation in English
This master thesis is focused on one-dimensional study of reciprocating compressor valve dynamics. For this purpose, a tool was developed, which is used to qualitatively evaluate the individual aspects of valve dynamics as well as their interaction. A mathematical model, which is implemented in the tool, is described in detail in this thesis.
Keywords
pístový kompresor, dynamika ventilu, interakce těleso-tekutina, proudění vzduchu, jednodimenzionální model
