On the fluctuating filtrate

Abstract

We show by the application of the ‘stick-slip' phenomenon, that, the filtrate through a porous medium could be oscillatory under low-intensity driving forces. The frequency of the oscillation is dependent on the nature of the porous medium and the external driving forces. It is, therefore, possible to characterize the medium by the use of low amplitude external driving forces.
