Abstract
Diplomová práce se zabývá experimentálním výzkumem nestacionárních proudových polí tkacích trysek. Pro měření je využita moderní anemometrická metoda PIV (Partical Image Velocimetry) a okrajově také LDA (Laser Doppler Anemometry). Pro možnost porovnání naměřených dat byly provedeny simulace v prostředí Fluent. Na základě naměřených dat je podrobně popsáno chování proudu ve stacionárním režimu a také vznik, vývoj a charakter proudu v pulzním režimu (rozběh, ustálení, doznívání). Práce se také zabývá experimentem při zachycení letícího útku a stanovením rychlosti jeho pohybu.
The main aim of diploma thesis is experimental jet flow research behind industrial weaving nozzle pneumatic weaving machinery. Study is based on modern PIV method (Particle Image Velocimetry). Results of these measurements help to understand needs of weaving nozzle construction, supply of compressed air and timing of control elements. In document is described full measuring system, its experimental disposition and device synchronizing procedure with solenoid valve. Thesis specifies data acquisition and processing. Results are presented also via graphic form and document behaviour of jet flow behind weaving nozzle throughout whole working cycle (start, standstill, and tail).
