  • EXPERIMENTAL STUDY ON GENERATION AND DISSIPATION MECHAMISIMS OF TURBULENCE INCIDE AND IN THE VICINITY OF POROUS MEDIA

抄録

A measuring method of fluid motion inside and in the vicinity of porous media made of silicon spheres is presented. Sodium iodide solution is used as the refraction index matching fluid. In order to capture pictures, a CCD camera and YAG laser are used. The velocity datum are obtained by analyzing the pictures using the superresolution PIV method. Some experimental results on the velocity field and turbulence kinematic energy are presented. Structure of the flow filed inside and in the vicinity of the porous media is discussed. Moreover generation and dissipation mechanisms of the turbulence are discussed.
