Analysis of anisotropic subgrid-scale stress for coarse large-eddy simulation
Kazuhiro Inagaki, Hiromichi Kobayashi
This study discusses the necessity of anisotropic subgrid-scale (SGS) stress in large-eddy simulations (LESs) of turbulent shear flows using a coarse grid resolution. We decompose…
Transport and modeling of subgrid-scale turbulent kinetic energy in channel flows
Kazuhiro Inagaki, Hiromichi Kobayashi
To develop a more convenient subgrid-scale (SGS) model that performs well even in coarse grid cases, we investigate the transport and modeling of SGS turbulent kinetic energy (here…
Role of various scale-similarity models in stabilized mixed subgrid-scale model
Kazuhiro Inagaki, Hiromichi Kobayashi
We investigate the physical role of various scale-similarity models in the stabilized mixed model [K. Abe, Int. J. Heat Fluid Flow, 39, 42 (2013); M. Inagaki and K. Abe, Int. J. He…
Higher-order realizable algebraic Reynolds stress modeling based on the square root tensor
Kazuhiro Inagaki, Taketo Ariki, Fujihiro Hamba
In this study, realizable algebraic Reynolds stress modeling based on the square root tensor [Phys. Rev. E \textbf{92}, 053010 (2015)] is further developed for extending its applic…
Energy transport due to pressure diffusion enhanced by helicity and system rotation in inhomogeneous turbulence
Kazuhiro Inagaki, Fujihiro Hamba
It is known that turbulent energy is rapidly transferred in the direction of the rotation axis in a rotating system, in comparison with the non-rotating case. In this study, this p…
Mechanism of mean flow generation in rotating turbulence through inhomogeneous helicity
K. Inagaki, N. Yokoi, F. Hamba
Recent numerical simulations showed that the mean flow is generated in inhomogeneous turbulence of an incompressible fluid accompanied with helicity and system rotation. In order t…
