An efficient bilinear interface reconstruction algorithm and consistent multidimensional unsplit advection scheme for accurate capturing of highly-curved interfacial shapes on structured grids

A new bilinear interface reconstruction algorithm (BLIC) is presented to capture highly-curved interfaces more accurately on structured grids without a significant increase in computational costs compared to the standard piecewise linear interface calculation (PLIC) methods. The new reconstruction algorithm uses the initial PLIC segment and...

Extreme aerated water-wave impacts on floating bodies: The relevance of air content in water on ship design loads

A deeper understanding of physics is required when the complexity of events increases. A complex event consists of many detailed interacting processes. The complete picture asks for an understanding of each of the processes individually.<br/>Numerical computing in the maritime industry is becoming more relevant due to the increase in usability...

Multi-fidelity Kriging extrapolation together with CFD for the design of the cross-section of a falling lifeboat

Surrogate modelling techniques such as Kriging are a popular means for cheaply emulating the response of expensive Computational Fluid Dynamics (CFD) simulations. These surrogate models are often used for exploring a parameterised design space and identifying optimal designs. Multi-fidelity Kriging extends the methodology to incorporate data...

Two-phase free-surface flow interaction with moving bodies using a consistent, momentum preserving method

The numerical prediction of two-phase flows with an interface is challenging, to a considerable extent because of the high density ratio at the interface. Numerical results become affected by momentum losses, diverging spurious interface velocities, free surface distortion, and even numerical instability. To prevent issues like these,...
