Experimental Investigation of the Percolation Behavior of Fine Particles Through Porous Media
摘要
This research investigates the percolation characteristics of fine spherical particles through static packed beds composed of larger particles. For our experiments, glass beads with a diameter of 0.5 mm are used as the smaller particles, and the diameter of the larger particles is adjusted to achieve a desired size ratio (R) ranging from 8 to 16. Experimental studies are conducted in a rectangular tank, which is filled with larger particles to form the packed bed and the fine particles are introduced from the top of the tank. During experiments, we capture high resolution images using a DSLR camera which are later processed in MATLAB for extracting data and analysis. By varying these listed parameters systematically, this study aims to identify the conditions under which percolation occurs. The primary objective of this research is to establish a relationship between the flow rate, bead size ratio, and their impact on percolation through the packed beds. This investigation holds significant importance for understanding granular material behavior and has implications for fluidization, filtration.
