Publisher: Springer

DOI: 10.1103/PhysRevLett.99.114504. An accurate prediction of turbulent flow inside/over a complex geometry has been one of the most important issues in fluid mechanics. Sagaut, P., Large Eddy Simulation for Incompressible. After introducing the fundamentals on compressible turbulence and the LES governing equations, the mathematical framework for the filtering paradigm of LES for compressible flow equations is established. Wall models in the large-eddy simulation of atmospheric surface layer flows. For the governing equations of compressible flow,. Large eddy simulation (LES) is a popular technique for simulating turbulent flows. This feature allows one to explicitly solve for the flows, see Favre averaged Navier-Stokes equations. Large Eddy Simulation for Incompressible Flows: An Introduction. Turbulence plays a very important role in the transport of mass, Applying the box-filtering operation to the incompressible Navier-Stokes equations, the equations governing the motion of the resolved scales in large-eddy simulation are given as follows:.

PACS numbers: 47.27 This is of considerable importance since many flows in practical applications are at high Reynolds number, numbers, under incompressible conditions, is to use large length scales. Alternatively, large eddy simulation (LES) may be used to analyze complex turbulent flows [6–8]. This book is a sequel to "Large Eddy Simulation for Incompressible Flows", as most of the research on LES for compressible flows is based on variable density extensions of models, methods and paradigms that were developed within the incompressible flow framework. Here we adopt this strategy and obtain .. With interfacial and turbulent flows. Since the lack of understanding of the nature of the small-scale motions of turbulent flows, the accuracy of available SFS models is not so satisfactory, which introduce considerable modeling errors in LES. Stull, An Introduction to Boundary Layer. Meteorology (Kluwer, Dordrecht, 1988). An implication of Kolmogorov's (1941) theory of self similarity is that the large eddies of the flow are dependant on the geometry while the smaller scales more universal. Two-phase turbulent flows occur in many technical processes in engineering, such as in chemical processes, pneumatic transport of particulates, air pollution control, circulating fluidized beds, and coal combustion.

Although formulation of mathematical models to simulate numerically such complex flows is a challenging task, many researches [3] simulated incompressible flows in complex geometries using large eddy simulation (LES), Zhang et al.
