On the identification of a vortex

Jinhee Jeong, +1 more
- 25 Feb 1995 - 
TL;DR: In this article, the authors propose a definition of vortex in an incompressible flow in terms of the eigenvalues of the symmetric tensor, which captures the pressure minimum in a plane perpendicular to the vortex axis at high Reynolds numbers, and also accurately defines vortex cores at low Reynolds numbers.

A new version of detached-eddy simulation, resistant to ambiguous grid densities

Philippe R. Spalart, +5 more
- 30 May 2006 - 
TL;DR: In this paper, the authors proposed the DES97 model, denoted DES97 from here on, which can exhibit an incorrect behavior in thin boundary layers and shallow separation regions, when the grid spacing parallel to the wall becomes less than the boundary-layer thickness.

Q1. What contributions have the authors mentioned in the paper "Detailed analysis of the flow within the boundary layer and wake of a full-scale ship" ?

This article presents a detailed numerical flow assessment of the boundary layer and wake of a full-scale cargo ship. The analysis method followed during this work has been a determinant factor for fast and efficient design of energy saving devices, propellers or rudders that work within the limits of the boundary layer of a ship. In particular, this thorough analysis avoided the necessity to use the commonly used practice of trial and error that is typically followed in the maritime industry.
