Relative diffusion of a pair of fluid particles in the inertial subrangeof turbulence

Turbulent diffusion of a pair of fluid particles in 3-dimensional homogeneous and isotropic turbulence was studied using a high-resolution direct numerical simulation (DNS)with 1024^3 grid points. The DNS showed that the mean square of the distance δx between the two fluid particles grows with time t as ～C∈t^3 in the inertial subrange, which is in agreement with Richardson (1926)and Obukhov (1941), where C≈0.7 and ∈ is the mean dissipation rate per unit mass. A simple Lagrangian closure approximation for is shown to be in good agreement with the DNS.journal articl

The Change of the Samurai's Premises in Jyonohashi-area, Part 3 A Study on the Samurai's Premises of the Fukui Castle Town, Part 25

This paper considers the changes of the samurai's premises in the Jyonohashi-area referring to the `FUKUIJYOKA-EZU'. The premises of the north side and the east side of the Jyonohashi-area were the areas that depended on reduction and the increase of the samurai between Genbun 4 from Jokyo 3. As for the three wards in the north side, constitution of the streets and the allotment of the premises of the whole area greatly changed later from the middle of the Edo era. In the same way as allotment of the premises, many samurai performed premises substitution from Jokyo 3 to Genbun 4. It was the same area, but, in the east side and the west, the changes of the samurai's premises were greatly different.departmental bulletin pape
