Towards Rapid Prototyping of Spray Injectors: A Regime-Agnostic Neural Operator Surrogate for Gas-Liquid Interface Evolution
Paolo Guida, Po-Han Chen, Hong G. Im +1
Spray atomisation rapidly creates large liquid-gas interfacial areas and is central to many industrial processes. However, predicting spray behaviour and surface area remains diffi…
Real-time control of multiphase processes with learned operators
Paolo Guida, Didier Barradas-Bautista
Multiphase flows frequently occur naturally and in manufactured devices. Controlling such phenomena is extremely challenging due to the strongly non-linear dynamics, rapid phase tr…
What it takes to break a liquid: analysis of the cavitation threshold in various media
Gianmaria Viciconte, Paolo Guida, Tadd T. Truscott +1
Cavitation has historically been related to parameters measured at equilibrium, such as vapor pressure and surface tension. However, nucleation might occur when the liquid is metas…
High-speed imaging and coumarin dosimetry of horn type ultrasonic reactors: influence of probe diameter and amplitude
Gianmaria Viciconte, Varaha P. Sarvothaman, Paolo Guida +2
Ultrasound driven cavitation is widely used to intensify lab and industrial-scale processes. Various studies and experiments demonstrate that the acoustic energy, dissipated throug…
Towards a general description of the cavitation threshold in acoustic systems
Gianmaria Viciconte, Paolo Guida, Tadd Truscott +1
Traditionally, the occurrence of cavitation has been related to the ratio between flow velocity and pressure gradient in the case of hydrodynamic cavitation, or some combination of…
