A New Dimensionless Friction Factor for Porous Media
Краткое описание
A new dimensionless parameter for expressing the ability of a porous material to transmit fluids through its interconnected pores is suggested. The new parameter is developed from the modification of the Hagen-Poiseuille and Darcy-Weisbach equations used for the flow of fluids in pipes. The modification is based on the assumption that a pipe is equivalent to an isotropic porous medium of circular cross section, in which the porosity is 100%. With this assumption, the new dimensionless transmission factor can be related to the porosity of the material. Experimentation has shown that the suggestion here is valid. The equipment used and the results of the experiment are also presented in this article.
