ADVANCED PROCESS AND DEVICE FOR STUDYING THE PROPERTIES OF A PERMEABLE MATERIAL

摘要

the process consists of placing a sample initially soaked with a first fluid in a container or cup (2) containing another fluid of different density and applycentrifugal force by rotating the bucket at the end of an arm (16) so as to study the movement of fluids in the sample in at least two distinct phases.in the first, we increase the rotational speed of the first fluid to drain out of the sample. in the second, we gradually decreases the speed of rotation.in order to avoid any interruption of the sample and to allow imbibition is always to maintain the fluid in contact with the sample.it is possible to determine the amount of fluid produced in the container (2) by centrifugation.you can also transfer the fluid in a chamber is variable within the same container, and a second rotating cup (6), for example.application to the study of capillary pressure and relative permeability of samples, for example.
