NON-DARCY FLOW THROUGH LARGE GRANULAR MEDIA
This paper presents the results of applying dimensional analysis to obtain a relationship between friction factor and Reynolds number for flows through porous media using a directly measurable parameter such as hydraulic radius R, which is equal to void ratio e divided by the specific surface So, as characteristic length. Using this friction factor—Reynolds number relationship, theoretical curves, which are similar to Moody diagram used for pipe flow, are developed and verified with the help of existing experimental data. The relationships existing between the permeability k, the linear parameter a, the non-linear parameter b, the hydraulic radius R and the media constants are also obtained theoretically and verified with the available experimental data.
