Effect of Convergent Angle on Nonlinear Flow through Porous Media
RESUMO
An experimental investigation on the effect of the convergent angle on nonlinear flow through porous media was studied in a converging permeameter. The scope of the present paper is to present the results of applying dimensional analysis to obtain a relationship between the friction factor and Reynolds number for flow in porous media with converging boundaries, using the volume diameter as the characteristic length, and also to develop an expression for a linear parameter and nonlinear parameter in terms of the volume diameter by the method of dimensional analysis. Using the friction factor and Reynolds number relationship, theoretical curves, which are similar to the Moody diagram used for pipe flow, are developed and verified with the help of existing experimental data. From the set of theoretical curves so obtained, the Reynolds number at which the friction factor and Reynolds number relationship deviates from Darcy's law and the Reynolds number at which turbulent flow is fully established are identified. In the present case, existing data of size 1.66 cm was used as media and water as fluid, to study the variation of the friction factor and Reynolds number with different ratios of the radii and for different convergent angles of a permeameter.
