Abstract: [eng] [cze]
The motivation of our work is the bubble generation from orifices of a gas distributor in bubble columns. Our interest is in the detail dynamics of bubble formation, namely in investigation of the synchronous and asynchronous modes of bubbling from multiple orifices. We considered the bubble formation both form a needle and an orifice on plate. We approached the problem with both the CFD and experiment. Cílem naší práce je výzkum tvorby bublin na otvorech distributoru plynu v probublávaných kolonách. Jedná se zejména o popis detailů dynamiky generace bublin, a to konkrétně výzkum synchronního a asynchronního módu probublávání z více otvorů. Uvažujeme přitom tvorbu bublin jak na jehle, tak na otvoru v patře. Pro řešení daného problému využíváme CFD simulace a experimenty.
