General circulation experiments with the primitive equations

Joseph Smagorinsky
- 01 Mar 1963 - 
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.

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.

Generation of Turbulent Inflow Data for Spatially-Developing Boundary Layer Simulations

T. S. Lund, +2 more
- 01 Mar 1998 - 
TL;DR: In this article, a method for generating three-dimensional, time-dependent turbulent inflow data for simulations of complex spatially developing boundary layers is described, which is essentially a variant of the Spalart method, optimized so that an existing inflow?outflow code can be converted to an inflow-generation device through the addition of one simple subroutine.

- 10 Apr 2003 - 
TL;DR: In this article, the authors present a new approach for generating artificial velocity data which reproduces first and second order one point statistics as well as a locally given autocorrelation function.
Trending Questions (1)
What type of combustion chamber is commonly used in axial compressor engines?

A recycling method is developed that improves the quality of the flow in a single stage calculation of an axial compressor, and indicates that future developments in both the recycling technique and computing power will bring simulations of axial compressors within reach of industry in the coming years.
