A simple experimental technique to measure tortuosity in packed beds

Abstract

In this article, a simple and inexpensive experimental technique easy to build in laboratory, for the measurement of tortuosity of a packed bedof inert particles, is described. Experimental values of the tortuosity were obtained with four different packed beds of sand. The experimentalresults obtained are in good agreement with the theoretical values of tortuosity in a porous media; and the data reported showed the tortuosityto increase with decrease in the void fraction of the packed bed as expected.
