EVALUATION OF THE CAPILLARY-ORIFICE MODEL OF HIGH-SPEED FLOW THROUGH POROUS MEDIA.

Abstract

The primary purpose was to determine whether the 'capillary-orifice model' of Blick (E. F. Blick, 'Highspeed flow through porous media', Ph. D. dissertation, Univ. of Oklahoma, 1963) would give experimental results that correlate to the flow through the media. The models under test were constructed from acrylic plastic tubing and 0.125-in. acrylic plastic sheet. Excellent correlation was obtained for Reynolds numbers greater than 1000. With a model of 0.50-inch tube diameter, the ratio of orifice diameter to tube diameter desired was 0.72. Improved correlation could possibly be obtained by basing the orifice spacing upon both mean pore diameter and porosity, especially in the case of porous media not formed from particles. The ratio of orifice diameter to tube diameter would seem to be statistically related to the pore size distribution. A Fortran program is given for use in data reduction with two mass-indicating flowmeters.
