MAGNETOHYDRODYNAMIC FLOWS IN POROUS-MEDIA II - EXPERIMENTAL RESULTS

Experimental data are presented for the pressure drop of a flowing con ducting fluid within a packed bed of spheres through a transverse magn etic field. pertinent background information is presented about flows in porous media followed by relevant details of the experiment apparat us and equipment. The data are presented and discussed and then compar ed with the predictions from the previously developed analytical model It is found that good agreement exists between the data when plotted in dimensionless form. As with the other equations for fluid flow in p orous media, the analytical forms specify behavior to within an experi mentally determined constant. A new constant, the Sanders constant, co ntained within the equation for the resistance ratio, is proposed. The experiment data are compared with the analytical model, and the best value of the Sanders constant is estimated.
