Dr Kalogirou is currently working towards broadening our understanding of the effect of surfactants on the complex behaviour of small-scale multi-layer flows. This work started as part of a Leverhulme Early Career Fellowship (Jan. 2017-Jan. 2020) and is mainly in collaboration with Dr Mark Blyth (UEA). The primary aim of the study is to suggest a mechanism for controlling multi-layer flows using surfactants, and ultimately to facilitate our ability to systematically control flows across scales.
As a PhD student working under the supervision of Prof Demetrios Papageorgiou (Imperial), Dr Kalogirou performed research that shed light on the role of insoluble surfactants on the interfacial instabilities encountered in two-fluid shear flows. The research followed a synergistic approach combining different techniques such as asymptotic analysis and numerical computations, with particular aim to explore the underlying nonlinear dynamics. An important result of this work was that in particular cases, the observed nonlinear wave solutions demonstrated good agreement with wave structures found in two-fluid shear flow experiments.
Dr Kalogirou has also worked on the mathematical and numerical modelling of nonlinear water waves and their impact on moving ships, in collaboration with Prof Onno Bokhove (Leeds). The research employed variational methods to derive appropriate equations governing the evolution of the free water surface, coupled to the dynamics of the ship. Fast and accurate numerical simulations have been performed based on a (dis)continuous Galerkin finite element methodology, with aim to investigate various problems including the generation and interaction of rogue waves and their impact on floating bodies such as wave-energy devices or ships. Nonlinear wave solutions have also been correlated to rogue waves observed in wave-tank experiments.
