With its cutting edge VOF modelling capabilities, OpenFOAM is the code of choice for a lot of marine and offshore applications, including offshore renewable energy (wind, wave and tidal), naval hydrodynamics and coastal protection. What these share is the requirement to simulate the interaction of water current, wind and waves with immersed structures (ships, rigs, wind turbines, wave energy generators etc), often including body movement (6DOF modelling). There is a very active UK community in Wave-Structure Interaction (WSI), particularly involved in the offshore renewable industry, and a substantial commitment to OpenFOAM use associated with this. One major activity is the CCP-WSI; Collaborative Computational Project in Wave-Structure Interaction, lead by Prof Deborah Greaves in U. Plymouth. CCPs are projects funded by the UK government to promote collaboration and networking in particular computational areas. I will talk about the various activities the CCP-WSI has run, including industrial and coding events and the highly successful Blind Test competitions, and also look to the future with the new CCP-WSI+; a follow-on project starting in September which will take over when the existing one ends. The new CCP-WSI+ will continue with the existing work, but also expand to include Full Coupled Wave-Structure Interaction (FCWSI) where the computational modelling includes linkage with structural and vibrational modelling of the immersed objects. I will also review other challenges and opportunities in the field, including exascale computation and optimisation.
Prof. Gavin Tabor is Associate Professor in CFD in the University of Exeter and is based at the Exeter (Streatham) campus. After a PhD in Computational Astrophysics he changed areas to undertake postdoctoral research in CFD at Imperial College, where he was involved in the early development of the OpenFOAM open source CFD code. In 2000 he was appointed to a lectureship at Exeter, developing a world-leading research group in CFD and teaching CFD and fluid dynamics at the UG level.
His research covers a wide range of topics within CFD, including turbulence, combustion, multiphase flow, and applications of CFD in a variety of areas such as biomechanics and renewable energy. Current research projects include work on Machine Learning and CFD for optimisation, solid fuel combustion, simulation of vortex separators used in Urban Drainage applications, simulation of design and manufacture of compact heat exchangers, and of course the ResIn project on floating wind turbines. He is a prominent member of the international OpenFOAM community involved in organising both the UK Users Group and the international Workshop; is a member of the IOP Computational Physics Group committee, and involved in the CCP-WSI collaboration Wave-Structure Interaction.

Title: Wastewater treatment plants, a challenge for CFD modelling: coupling multiphase flow hydrodynamic and complex biological processes.
Dr. Sergio Chiva is associate professor at Universitat Jaume I of Castellón (Spain) in the Fluid Mechanic area within the Department of Mechanical and Construction Engineering. He is Industrial Engineering from Universitat Politècnica de València, and he completed his PhD in the Department of Chemical and Nuclear Engineering at the same university, developing thermohydraulic models for codes applied to the nuclear industry. He has focused his work in multiphase flow CFD modelling and experimental work applied to chemical, energy and wastewater treatment industry, being co-founder of the Multiphase Flow Group and head of the Chair devoted to the Water Cycle Management at Universitat Jaume I. His group has developed a large number of CFD models to study processes, units and equipment in WWTP, coupling complex biochemical processes and hydrodynamic behaviour.
Norberto Fueyo and Ana Cubero - University of Zaragoza (Spain)
Title: OpenFOAM at Universidad de Zaragoza: from “have-it” to “hacking”
This talk narrates our research group’s trajectory in the use of OpenFOAM, from intrigued potential users (“we have it”) to writing new solvers (“hackers”). The paper will present some of our applications of OpenFOAM in the fields of chemically-reacting and multiphase flows, and how the needs of industrial-problem modelling led to the development of models and algorithms. The presentation will focus on combusting flows (with the adaptation of a Flamelet Generated Manifold model), solid oxide fuel cells (with the creation of a transport properties library) and multiphase flows (with the development of a new OpenFOAM Eulerian-Eulerian solver).
Norberto Fueyo (PhD Industrial Engineering) is a professor in Fluid Mechanics at the University of Zaragoza, where he leads the Numerical Fluid Dynamics Group, GFN. He took his PhD on CFD at Imperial College, London, where he was one of the last PhD students to be supervised by Professor DB Spalding. His research interests include CFD and energy systems, including the simulation of multiphase flows and of chemically reacting flows. He is the author of over 55 papers in international journals.
Ana Cubero (PhD Physics) is a post-doctoral researcher with the Numerical Fluid Dynamics group at University of Zaragoza. She has extended her 2008 PhD research on (single-phase) consistent momentum interpolation to Eulerian-Eulerian multiphase flows, and has written an alternative multiphase solver for OpenFOAM. Since then, she has taken a keen interest in the simulation of reactive flows (including the implementation in OpenFOAM of a Flamelet Generated Manifold method), and in industrial flows using OpenFOAM.
