TL;DR: In this article, the effects of Reynolds number in the nominal case of an infinitely long and non-confined cylinder in a smooth oncoming flow are discussed, from about Re = 47 to 2 x 10(5), i.e., from the onset of vortex shedding up to the end of the subcritical regime.

TL;DR: This paper gives a review of the first hierarchical and purely matrix-based approach, algebraic multigrid (AMG), which can directly be applied to efficiently solve various types of elliptic partial differential equations discretized on unstructured meshes, both in 2D and 3D.

TL;DR: A review of modeling of NOX reactions in combustion systems, with an emphasis on coal-fired systems, including current NO X control technologies, NO X reaction processes, and techniques to calculate chemical kinetics in turbulent flames are reviewed in this article.

TL;DR: In this paper, a method to perform large-eddy simulations around complex boundaries on fixed Cartesian grids is presented, which is applicable to boundaries of arbitrary shape, does not involve special treatments, and allows the accurate imposition of the desired boundary conditions.

TL;DR: The Hamilton-Jacobi level set formulation of the equations of motion for propagating interfaces has been introduced recently by Osher and Sethian as mentioned in this paper, which allows fronts to self-intersect, develop singularities, and change topology.
