20.500.12556/RUL-128620 Challenges of numerical simulations of cavitation reactors for water treatment – an example of flow simulation inside a cavitating microchannel The research on the potential of cavitation exploitation is currently an extremely interesting topic. To reduce the costs and time of the cavitation reactor optimization, nowadays, experimental optimization is supplemented and even replaced using computational fluid dynamics (CFD). This is a very inviting opportunity for many developers, yet we find that all too often researchers with non-engineering background treat this "new" tool too simplistic, what leads to many misinterpretations and consequent poor engineering. The present paper serves as an example of how complex the flow features, even in the very simplest geometry, can be, and how much effort needs to be put into details of numerical simulation to set a good starting point for further optimization of cavitation reactors. Finally, it provides guidelines for the researchers, who are not experts in computational fluid dynamics, to obtain reliable and repeatable results of cavitation simulations. cavitation computational fluid dynamics numerical simulation Venturi channel microchannel kavitacija računska dinamika fluidov numerična simulacija venturijeve cevi mikrokanal true false true Angleški jezik Slovenski jezik Članek v reviji 2021-07-21 10:03:15 2021-07-21 10:03:18 2023-03-23 03:34:19 0000-00-00 00:00:00 2021 0 0 10 str.
