On the Applicability of Lattice Boltzmann Single-Phase Models for the Simulation of Wave Impact in LNG Tanks

Abstract

This contribution addresses the applicability of an efficient lattice Boltzmann-based single-phase free-surface model for the simulation of wave impact on the side walls of 2-D containers. The computational efficiency of the method is known to allow for very short turnaround times, but wave impact simulations have not been investigated in detail yet. Results for a selected wave impact case are discussed, the convergence behavior in space and time is analyzed, and limitations of the single-phase free-surface model are revealed. The results show that lattice Boltzmann method (LBM)-based single-phase free-surface models are a viable tool for predicting the impact wave behavior, but the quality of the pressure signal is limited, because of the absence of air in the simulations.

Using an Interactive Lattice Boltzmann Solver in Fluid Mechanics Instruction

“…Even though he is not part of the ELBE team anymore, he's occasionally using ELBE for gaining additional fluid mechanical insight for his current research project, or for demonstration purposes. Moreover, he published his work for the above-mentioned research project in three different journal publications [30,42,43]. On top, he presented the results in front of a large audience at an international conference.…”
