Multiphase flows are found everywhere, in nature and in industry.  While earlier CFD software dealt mainly with single phase flow, advanced models have now been incorporated in many codes which make it possible to successfully simulate configurations involving more than one phase, whether for analysis or to design new industrial equipment.  However, these simulations, like the physics of multiphase flow itself, remain often complex and it is important to be aware of the concepts which underpin the models and their applications.  

This webinar has been designed to provide a general introduction to these concepts.  As such, it focuses on the physics of the flow and the broad modelling approaches, away from the details of implementation which would be code-specific.  As a result of this introduction, attendees should gain a broad understanding of the topic, which will help them to further explore multiphase flow CFD activities.

Nicolas Tonello

Nicolas TonelloAfter receiving a PhD in Aerospace Engineering at The University of Michigan, Ann Arbor, MI, USA, specialising in detonations and supersonic reactive flow, Dr. Nicolas Tonello worked in the USA for several years developing multiphase, reactive flow CFD software for aerospace applications. After moving to the UK to take up a position leading the implementation of two-phase flow Eulerian modelling and radiation for a leading CFD software provider, Dr Tonello founded Renuda in the UK and is now director of Renuda in the UK and France, which specialises in developing software applications and conducting fluid flow and thermal studies.  Dr Tonello has 20+ years’ experience in CFD and fluid mechanics applied to a large variety of industrial problems and flow regimes, from nuclear to the process industry, with a keen interest and expertise in High Performance Computing (HPC).
