Free-surface flows are very important in many fields. Compared with volume of fluid methods, level set methods are more accurate. In this paper, we develop a coupled lattice Boltzmann and particle level set method to simulate free-surface flows. The effectiveness of this model is verified by simulating the coalescence of two stationary droplets, evolution of an initially circular fluid patch, and the classical breaking-dam case. Results show that this model can be applied to real world simulations with satisfactory accuracy.

“…Consequently, the lattice Boltzmann VOF advection scheme can be considered as a specialized, geometry-based VOF method on the basis of a mesoscopic advection model. Note that, in contrast to higher order schemes [13], the normal vector information is not considered here. Nevertheless, the model has been shown to perform well for many different free-surface scenarios [14,15] and also in the context of GPU implementations [16].…”

This contribution is dedicated to demonstrating the high potential and manifold applications of state-of-the-art computational fluid dynamics (CFD) tools for free-surface flows in civil and environmental engineering.All simulations were performed with the academic research code ELBE (efficient lattice boltzmann environment, http://www.tuhh.de/elbe). The ELBE code follows the supercomputing-on-the-desktop paradigm and is especially designed for local supercomputing, without tedious accesses to supercomputers. ELBE uses graphics processing units (GPU) to accelerate the computations and can be used in a single GPU-equipped workstation of, e.g., a design engineer. The code has been successfully validated in very different fields, mostly related to naval architecture and mechanical engineering. In this contribution, we give an overview of past and present applications with practical relevance for civil engineers. The presented applications are grouped into three major categories: (i) tsunami simulations, considering wave propagation, wave runup, inundation and debris flows; (ii) dam break simulations; and (iii) numerical wave tanks for the calculation of hydrodynamic loads on fixed and moving bodies. This broad range of applications in combination with accurate numerical results and very competitive times to solution demonstrates that modern CFD tools in general, and the ELBE code in particular, can be a helpful design tool for civil and environmental engineers.

“…Even then, dynamic simulation of breaking‐in‐progress from the first principles is a formidable numerical task as it has to describe the two‐phase fluid behavior, with air bubbles below and sea droplets above the mean interface. With the rapid growth of computer power, such dynamic wave models became available over the last decade [e.g., Abadie et al , 1998; Dalrymple and Rogers , 2006; Iafrati , 2009; Janssen and Krafczyk , 2010; Lakehal and Liovic , 2011], but still they are only capable of simulating only a few periods of wave evolution.…”

The article introduces the Special Issue of the Journal of Geophysical Research– Oceans which is based on the papers presented at or related to the new session of the General Assembly of the European Geosciences Union, first conducted in 2011. Topic of the session on the Surface Waves and Wave‐Coupled Effects highlights a new dimension of the present state of wind‐wave research. The surface waves is an important oceanographic topic in its own right, but it is also rapidly becoming clear that many large‐scale geophysical processes are essentially coupled with the surface waves, and those include climate, weather, tropical cyclones and other phenomena in the atmosphere and many issues of the upper‐ocean mixing below the interface.
