粒状層上の振動流によって誘起される乱流諸量に関する実験的研究

Description

The internal and external fluid flows induced by oscillatory flow over a porous medium were measured by the Particle Tracking Velocimetry (PTV) with matching the refraction index method using two high-speed cameras. The characteristics of spatial variance of velocity components were shown in detail with the time phase variance. Further, the properties of the turbulent quantities such as turbulent kinematic energy and the Reynolds' stress were presented and the relationship among the turbulence properties, the Reynolds' number, and the KC number was discussed.
