Biography
I am an Assistant Professor in the Department of Mechanical, Materials and Manufacturing Engineering at the University of Nottingham. I received a Master Degree in Mechanical Engineering from the University of Bologna, Italy, and a PhD in Energy Engineering from the same institution in 2012. From 2013 to 2017 I was a post-doc research assistant at the Laboratory of Heat and Mass Transfer, EPFL, Switzerland, where our research into numerical and theoretical modelling of microchannel flow boiling was funded by the Swiss National Science Foundation. Prior to joining the UoN, I was a post-doc research associate in the Chemical Engineering Dept of Imperial College London where I worked on the numerical modelling of wax deposition in crude oil flows.
I am a member of the Virtual International Research Institute of Two-Phase Flow and Heat Transfer (VIR2AL), a portal where many international labs share their experimental and numerical data for two-phase flows and heat transfer, and where I curate an open-access tutorial on OpenFOAM.
I am Subject Editor (Heat and Mass Transfer) for Elsevier's journal Chemical Engineering Research and Design (ChERD), and Guest Editor in MDPI-Fluids for the Special Issue "Recent Advances in Single and Multiphase Flows in Microchannels" (link).

Expertise Summary
My research activity focuses on the investigation of the many fundamental mechanisms and phenomena governing multiphase flows, heat transfer, phase change and phase separation in confined geometries. My field of expertise spans across:
- Multiphase flows (both macro and microscale)
- Phase change/separation
- Thermo-fluid dynamics
- Multiphase computational fluid dynamics
- Use/development of CFD tools (ANSYS Fluent, Openfoam, Basilisk, in-house codes in Matlab/Python)
- Theoretical modelling of thin film flows and solution of the resulting ODEs

Research Summary
Boiling flows in capillary channels
Heat and mass transport in microchannels is key to diverse applications that span many disciplines in science and engineering, from mechanical, chemical, energy, and environmental engineering, to biological and medical science. My research in this field aims to characterise the fluid mechanics and heat transfer associated with long gas bubbles propagating in noncircular channels in both adiabatic and diabatic (boiling) conditions, using a combination of theoretical and computational methods; check out our most recent publications:

- M. Magnini, O. K. Matar, Int J Heat Mass Transfer 150 (2020) 119322. Link
This research is now funded by a £1.6M EPSRC grant (GoW) with Imperial College and Brunel University.
Molecular Dynamics analysis of nucleate boiling
With colleagues at Imperial College (Prof. Matar) and Brunel University London (Dr. E. Smith), we are working on the fundamental analysis of nucleate boiling over textured surface in order to inform the engineering design of heat transfer components. Check out our latest publication here:
- A. Lavino et al., Langmuir 37 (2021) 5731. Link
Evaporation in porous media for thermal management of fuel cells
With colleagues at EPFL (Prof. Sophia Haussener), we are developing advanced computational tools for the pore-scale numerical simulation of water evaporation within gas diffusion layers of PEM fuel cells, which provides simultaneous cooling and humidification of the fuel cell. Check out our most recent publication:

Two-phase flows in millimetric channels
With colleagues at Imperial College London (Prof. Matar) and Princeton University (Prof. Stone), we are studying the dynamics of thin films and long bubbles transported in channels of mm-size, in a regime where viscous, capillary and buoyancy effects all play a role. Within horizontal channels, buoyancy effects elevate the bubble above the channel centreline and tend to ovalize the bubble cross-section. In vertical channels, interesting different dynamics are observed depending on the direction of the bulk liquid flow. Our most recent publications are available here:
