MAGNETIC-RESONANCE-IMAGING OF LAMINAR-FLOW IN POROUS TUBE AND SHELL SYSTEMS

Magnetic resonance imaging (MRI) was used to measure noninvasively the steady, incompressible, laminar fluid flow in an inorganic porous tube and shell module. The porous tube module was operated in closed-end or "dead-end" mode for Reynolds numbers of 100 and 200, based on the tube radius. An MRI spin-echo, time-of-flight (TOF) technique was implemented and the results were compared to those of Stahlberg et al. (1986) and Pangrle et al. (1991). Stahlberg et al. (1986) predicted the signal intensity generated by flowing protons using the TOF technique and Pangrle et al. (1991) presented a theoretically based, numerical method for predicting fluid velocities and pressures in porous tube and shell systems. The experimental measurements agreed favorably with both the values predicted by the MRI, TOF theory and the axial velocity values from the numerical method.
