Numerics of the lattice Boltzmann method: Effects of collision models on the lattice Boltzmann simulations
TL;DR: The ELBE scheme is the most inferior among the LB models tested in this study, thus is unfit for carrying out numerical simulations in practice and the MRT and TRT LB models are superior to the ELBE and LBGK models in terms of accuracy, stability, and computational efficiency.
Numerical investigation of angle of attack profile on propulsion performance of an oscillating foil
Qing Xiao,Wei Liao +1 more
TL;DR: In this paper, the effects of effective angle of attack (AOA) profile on an oscillating foil thrust performance were studied using a computational method. And the authors found that the degradation of thrust force and efficiency with sinusoidal pitching/plunging oscillation, at higher St, is effectively alleviated or removed when the AOA is imposed as a cosine profile.

Euler calculations with embedded Cartesian grids and small-perturbation boundary conditions
TL;DR: This study examines the use of stationary Cartesian mesh for steady and unsteady flow computations and shows the practical usefulness of the embedded Cartesian grids with the small-perturbation boundary conditions approach.
