“OpenFOAM framework for mixtures with partially miscible components”

Keynote_Germann-small

Prof. Dr. Natalie Germann
Technical University of Munich
Germany

Many flows encountered in industrial applications are composed of several components. Important factors affecting the mass- and momentum transport of mixtures include the physicochemical and microstructural properties of the individual components as well as their degree of miscibility. In this keynote, I present a robust and versatile OpenFOAM framework for the simulation of mixtures with partially miscible components. By using advanced physical-based phase field models, we can reliably predict the interfacial dynamics and mixing characteristics of mixtures, as we have confirmed through validation against numerical benchmark data and in-house microfluidics experiments. Future work will focus on the simulation of real-world technical processes where partial miscibility play a crucial role, such as liquid-liquid extraction.

 

 

“The Collaborative Computational Project in Wave Structure Interaction (CCP-WSI)”

Keynote-Greaves

Prof. Deborah Greaves
University of Plymouth
United Kingdom

The Collaborative Computational Project on Wave Structure Interaction (CCP-WSI) is funded by the Engineering and Physical Sciences Research Council (EPSRC). Complex wave structure interaction (WSI) challenges are significant in the offshore renewable energy sector and in the protection of coastal communities, both of which are strategic priorities for the UK. Established in 2015 and extended with additional funds and partners in 2020, the CCP-WSI’s overarching aim is to build a community of researchers and developers and to provide a focus for software development and code rationalisation with applications in these UK priority areas.

 

 

“Recent Progress in the Evaluation of Impact Pressures”

Keynote-Dias

Prof. Frédéric Dias
University College Dublin
Ireland

Slamming, the violent impact between a liquid and solid, has been known to be important for a long time in the ship hydrodynamics community. More recently, applications ranging from the transport of liquefied natural gas (LNG) in LNG carriers to the harvesting of wave energy with oscillating wave surge converters have led to renewed interest in the topic. The main reason for this renewed interest is that the extreme impact pressures generated during slamming can affect the integrity of the structures involved. Slamming fluid mechanics is challenging to describe, as much from an experimental viewpoint as from a numerical viewpoint, because of the large span of spatial and temporal scales involved. Even the physical mechanisms of slamming are challenging: What physical phenomena must be included in slamming models? An important issue deals with the practical modeling of slamming: Are there any simple models available? Are numerical models viable? In this keynote, I describe the loading processes involved in slamming and highlight unresolved issues worthy of further research, especially from a numerical viewpoint.
