The nonlinear stability of two-fluid Couette flows is studied using a novel evolution equation whose dynamics is validated by direct numerical simulation (DNS). The evolution equation incorporates inertial effects at arbitrary Reynolds numbers throug... Read More about Capturing nonlinear dynamics of two-fluid Couette flows with asymptotic models.

Nonlinear dynamics of surfactant-laden two-fluid Couette flows in the presence of inertia (2016)
Journal Article
Kalogirou, A., & Papageorgiou, D. T. (2016). Nonlinear dynamics of surfactant-laden two-fluid Couette flows in the presence of inertia. Journal of Fluid Mechanics, 802, 5-36. https://doi.org/10.1017/jfm.2016.429

The nonlinear stability of immiscible two-fluid Couette flows in the presence of inertia is considered. The interface between the two viscous fluids can support insoluble surfactants and the interplay between the underlying hydrodynamic instabilities...

Mathematical and Numerical Modelling of Wave Impact on Wave-Energy Buoys (2016)
Presentation / Conference Contribution
Kalogirou, A., & Bokhove, O. (2016, June). Mathematical and Numerical Modelling of Wave Impact on Wave-Energy Buoys. Presented at ASME 2016 35th International Conference on Ocean, Offshore and Arctic Engineering, Busan, South Korea

We report on the mathematical and numerical modelling of amplified rogue waves driving a wave-energy device in a contraction. This wave-energy device consists of a floating buoy attached to an AC-induction motor and constrained to move upward only in...

Variational finite element methods for waves in a Hele-Shaw tank (2016)
Journal Article

The damped motion of driven water waves in a Hele-Shaw tank is investigated variationally and numerically. The equations governing the hydrodynamics of the problem are derived from a variational principle for shallow water. The variational principle...

© Cambridge University Press 2016. Variational methods are investigated asymptotically and numerically to model water waves in tanks with wave generators. As a validation, our modelling results using (dis)continuous Galerkin finite element methods wi... Read More about Variational water wave modelling: from continuum to experiment.
