Role of pressure in turbulence
Toshiyuki Gotoh, Tohru Nakano
There is very limited knowledge of the kinematical relations for the velocity structure functions higher than three. Instead, the dynamical equations for the structure functions of…
Local properties of extended self-similarity in 3D turbulence
Daigen Fukayama, Tohru Nakano, Alexander Bershadskii +1
Using a generalization of extended self-similarity we have studied local scaling properties of 3D turbulence in a direct numerical simulation. We have found that these properties a…
Longitudinal Structure Functions in Decaying and Forced Turbulence
Daigen Fukayama, Toshihiro Oyamada, Tohru Nakano +2
In order to reliably compute the longitudinal structure functions in decaying and forced turbulence, local isotropy is examined with the aid of the isotropic expression of the inco…
Probability Density Function of Longitudinal Velocity Increment in Homogeneous Turbulence
Naoya Takahashi, Tsutomu Kambe, Tohru Nakano +2
Two conditional averages for the longitudinal velocity increment u_r of the simulated turbulence are calculated: h(u_r) is the average of the increment of the longitudinal Laplacia…
Conditional Averages and Probability Density Functions in the Passive Scalar Field
Naoya Takahashi, Tsutomu Kambe, Tohru Nakano +2
Two conditional averages for the increment Delta(x,x+r) = T(x)-T(x+r) of the scalar field are estimated for DNS data: H(Delta)=<nabla^2 Delta(x,x+r)|Delta(x,x+r)> and G(Delta)=<|na…
