Most widely held works by S Balachandar

IUTAM symposium on computational approaches to multiphase flow : proceedings of an IUTAM symposium held at Argonne National Laboratory, October 4-7, 2004 by S Balachandar( )

17 editions published in 2006 in English and held by 443 WorldCat member libraries worldwide

The book provides a broad overview of the full spectrum of state-of-the-art computational activities in multiphase flow as presented by top practitioners in the field. It starts with well-established approaches and builds up to newer methods. These methods are illustrated with applications to a broad spectrum of problems involving particle dispersion and deposition, turbulence modulation, environmental flows, fluidized beds, bubbly flows, and many others

Spurious modes in spectral collocation methods with two non-periodic directions by S Balachandar( Book )

6 editions published in 1992 in English and held by 99 WorldCat member libraries worldwide

Collocation implementation of the Kleiser-Schumann's method in geometries with two non-periodic directions is shown to suffer from three spurious modes--line, column and checkerboard--contaminating the computed pressure field. The corner spurious modes are also present but they do not affect evaluation of pressure related quantities. A simple methodology in the inversion of the influence matrix will efficiently filter out these spurious modes. Spectral methods; Spurious modes

Inviscid instability of streamwise corner flow by S Balachandar( Book )

9 editions published in 1993 in English and held by 99 WorldCat member libraries worldwide

Linear stability of the incompressible flow along a streamwise corner is studied by solving the two-dimensional eigenvalue problem governed by partial differential equations. It is found that this fully three-dimensional flow is subject to inviscid instability due to the inflectional nature of the streamwise velocity profile. The higher growth rates for the inviscid instability mode, which is symmetric about the corner bisector, as compared to the viscous Tollmien-Schlichting instability operative away from the corner is consistent with the experimental findings that the corner flow transitions to turbulence earlier than the two-dimensional Blasius flow away from the corner.

Probability distribution functions in turbulent convection by S Balachandar( Book )

5 editions published in 1991 in English and held by 87 WorldCat member libraries worldwide

Results of an extensive investigation of probability distribution functions (pdfs) for Rayleigh-Benard convection, in the hard turbulence regime, is presented. It is seen that the pdfs exhibit a high degree of internal universality. In certain cases this universality is established within two Kolmogorov scales of a boundary. A discussion of the factors leading to universality is presented

Analysis and modeling of buoyancy generated turbulence using numerical data by Sharath Girimaji( Book )

4 editions published in 1997 in English and held by 86 WorldCat member libraries worldwide

Rayleigh-Bernard convection offers a unique flow situation in which buoyancy-generated turbulence can be studied in isolation, free of the complicating influence of shear production of turbulence. The objective of this paper is to examine and model important aspects of buoyancy-generated turbulence using direct numerical simulation (DNS) data of Rayleigh-Bernard convection. In particular, we examine the pressure-strain and pressure temperature-gradient correlations, turbulent transport of Reynolds stress, and assumptions pertaining to algebraic modeling of thermal flux and Reynolds stress

Optimal Large Eddy Simulation of Turbulence by Robert deLancey Moser( Book )

2 editions published in 2004 in English and held by 2 WorldCat member libraries worldwide

Optimal LES modeling is a new approach to the development of subgrid models of turbulence. It has been found to produce accurate LES simulations when based on reliable statistical information. Now, the primary effort in optimal model development is the determination of this statistical information from theoretical considerations, with minimal empirical input. The validity of the theoretically determined statistics is being tested against experimental and DNS data. When small-scales are isotropic, Kolmogorov theory, the quasi-normal approximation and a dynamic procedure allow optimal models to be constructed with no empirical input. Such models have been found to perform well, though the dynamic procedure has not yet been tested in this context. Tests using channel flow DNS show that, except for a region very near the wall, the quasi-normal approximation is valid. Further, for the log-region, a representation for the anisotropy and inhomogeneity of the statistics is being developed. Thus, the above modeling approach can be adapted to near-wall turbulence, except for the thin viscous region. To handle this wall layer, a filtered boundary optimal LES model is being developed and tested
