Regime-Aware Coupled Orchestration of Neural Operator Specialists for Multiphysics Dynamics
Paolo Guida, Vijayamanikandan Vijayarangan, Hong G. Im +1
Real-world physics often unfolds over a variety of characteristic lengths and time scales. These non-uniformities are among the main reasons numerical simulations remain expensive…
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…
Multi-Objective Molecular Generation with Frequency-Controlled Evolutionary Dynamics
Elia Colleoni, Paolo Guida, Didier Barradas-Bautista +1
Molecule generation methods that leverage generative models have been successfully applied to drug discovery. However, they often require extensive pre-training, suffer statistical…
Predicting The Evolution of Interfaces with Fourier Neural Operators
Paolo Guida, William L. Roberts
Recent progress in AI has established neural operators as powerful tools that can predict the evolution of partial differential equations, such as the Navier-Stokes equations. Some…
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…
