Cavitation flow and broadband noise source characteristics of NACA66 hydrofoil with a V groove on the suction surface
TL;DR: In this article , a V groove on the suction surface is proposed to investigate the cavitation flow and noise sources of a NACA66 hydrofoil, and the results show that the V groove significantly affects Mode 2, which represents a change in velocity distribution in the flow field characteristics.

General circulation experiments with the primitive equations
TL;DR: In this article, an extended period numerical integration of a baroclinic primitive equation model has been made for the simulation and the study of the dynamics of the atmosphere's general circulation, and the solution corresponding to external gravitational propagation is filtered by requiring the vertically integrated divergence to vanish identically.

Subgrid-scale stress modelling based on the square of the velocity gradient tensor
Franck Nicoud,F. Ducros +1 more
TL;DR: In this paper, a subgrid scale model is proposed for large eddy simulations in complex geometries, which accounts for the effects of both the strain and the rotation rate of the smallest resolved turbulent fluctuations.

The design and application of upwind schemes on unstructured meshes
TL;DR: Cell-centered and mesh-vertex upwind finite-volume schemes are developed which utilize multi-dimensional monotone linear reconstruction procedures which differ from existing algorithms (even on structured meshes).
