Marco Colombo

Marco Colombo is a Lecturer in Fluid Mechanics at the Department of Mechanical Engineering, University of Sheffield, School of Mechanical, Aerospace and Civil Engineering. He joined the university in late 2021 and focuses on computational fluid dynamics (CFD) for multiphase flows in nuclear systems.

• BSc: Energy Engineering, Politecnico di Milano
• MSc: Nuclear Engineering, Politecnico di Milano
• PhD: Politecnico di Milano (2013)

His research specializes in Thermo-fluid dynamics of multiphase flows, particularly nuclear thermal hydraulics, boiling heat transfer, passive cooling systems, and two-phase flow instabilities. He employs advanced CFD techniques, including Eulerian-Eulerian and LES models, to study bubbly flows and reactor cooling dynamics.

Recent publications highlight his work on

• Morphology-adaptive multifluid CFD for bubbly flows
• Generalized multiphase modeling (GEMMA) for multiscale flows
• Benchmarking turbulence closures in nuclear reactor applications
• Frictional pressure drop correlations in helical tubes

Scientific achievements include an EPSRC Fellowship to address gas-liquid flow regime modeling. Collaborators span institutions such as the University of Leeds and Politecnico di Milano.
