A tensorial approach to computational continuum mechanics using object-oriented techniques
TLDR
The implementation of various types of turbulence modeling in a FOAM computational-fluid-dynamics code is discussed, and calculations performed on a standard test case, that of flow around a square prism, are presented.

Mathematical and Physical Constraints on Large-Eddy Simulations
Abstract:We examine the mathematical constraints on the filtering operation in large-eddy simulation (LES), and the physical constraints on the formulation of subgrid scale (SGS) models. The
A comparative study of subgrid scale models in homogeneous isotropic turbulence
Recently, a number of studies have indicated that Large Eddy Simulation (LES) models are fairly insensitive to the adopted Subgrid Scale (SGS) models. In order to study this and to gain further
Comparison of LES of steady transitional flow in an idealized stenosed axisymmetric artery model with a RANS transitional model.
TLDR
The present study demonstrated the power of LES methods, although they were computationally more costly, and added further evidence of the promise of the RANS transition model used here, previously tested in pulsatile flow on a similar model.
Elliptical galaxy cooling flows without mass drop-out
The existence of a hot X-ray emitting gas phase in giant elliptical galaxies has long been recognized, but its structure and dynamics are still controversial. We explore the possibility that the gas
