A testing apparatus was developed for the determination of the change in
permeability of coarse porous media subjected to a decrease in porosity
.
literature survey was conducted to establish the design criteria for the
flow and loading tests. The mthemaUcal model describing flow through
course porous media was further developed on a theoretical basis by
postulating the layered medium model. Ihis model is a means by which
the variability of the particle sizes in the medium is taken into
account.
The design, construction and operation of the testing apparatus is
des:rvx-d. The specimen tested was laded up uo 3,45 MPa; consequently
'
the Fbrcheimer aquation in the form of K , Ci/R + Cg was found to
yield repeatable values for tiic turbulent friction factor C2, thus
providing a means of predicting the change in permeability if the change
in porosity and effective particle diameter are known.
