NMR IMAGING EXPERIMENTS FOR THE VERIFICATION OF STOCHASTIC TRANSPORT-THEORY

Nuclear magnetic resonance (NMR) imaging techniques were investigated as a means to obtain velocity field measurements for the verification of a stochastic transport theory. A modified stimulated-echo pulse seq uence was used to make velocity images in an aperiodic heterogeneous p orous medium. Construction of the velocity covariance from measurement s of the fluctuating velocity has demonstrated that nuclear magnetic r esonance imaging is a valuable tool for obtaining experimental data fo r the examination of existing stochastic transport theory.
