Abstract
Pulsed gradient NMR techniques are presented here. They allow the stud y of multiphase flow in pipes as well as porous media. The main advant ages are the possibilities of studying non transparent media at small length scales. We show that it is possible to obtain local information on the fluid flow, such as velocity profiles in two phase systems, or maps of distribution of displacement probabilities in heterogeneous p orous media.
