Cavitation is mostly unwanted in applications due to its unpredictable and distorting effect on fluid flow. On the other hand, its modelling is expensive in terms of time and computational power in general. Regarding this a tendency for using an open source software such as OpenFOAM is emerging as a promising tool for both predicting and analyzing cavity formation. In this study, validation and verification of an OpenFOAM solver is investigated for cavitation in microchannels. Experiments are carried out as well for comparison with computational results. During the experiments the cavity formation was efficiently captured by observing the fluorescent particle flow. Overall, computational and experimental results are compared to investigate the capability of OpenFoam for the chosen conditions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
