Experimental study on the influence of a T-foil and bulbous bow on the resistance and motion in regular head waves of trimarans
TL;DR: In this paper , the effects of a T-foil and bulbous bow configuration on the performance of a trimaran's performance were investigated through model tests, and it was shown that a Tfoil with a large aspect ratio is particularly effective in mitigating the heave and pitch motions and reducing the total resistance to waves.

Improved two-equation k-omega turbulence models for aerodynamic flows
TL;DR: In this article, two new versions of the k-omega two-equation turbulence model are presented, the baseline model and the Shear-Stress Transport model, which is based on the BSL model, but has the additional ability to account for the transport of the principal shear stress in adverse pressure gradient boundary layers.
