Abstract: Field cycling magnetic resonance based method and apparatus to measure and analyze flow properties in flowing complex fluids. The method consists on: 1) polarizing NMR active spins in a magnetic field region, 2) relaxing the plurality of individual macroscopic magnetizations in a second magnetic field region of variable intensity, 3) measuring the total macroscopic magnetization in a third magnetic field region on an NMR measurement module, and 4) reading the multidimensional data matrix with a tangible computer readable medium. The apparatus consists on: 1) a first magnet with constant magnetic field intensity, 2) a second magnet with a variable magnetic field intensity and time, 3) a third magnet having radio frequency antennas and field gradient coils (NMR module), and 4) a computing digital processor.

Abstract: Rotating frame magnetic resonance based method and apparatus to measure and analyze flow properties in flowing complex fluids. The method consists on: 1) polarizing NMR active spins in a magnetic field region, 2) relaxing the plurality of individual macroscopic magnetizations in a second magnetic field region, wherein a plurality of radiofrequency pulses are irradiating said phases of said multiphasic fluid, wherein phase individual rotating frame relaxation times weight magnetization of said individual phases at said downstream end, wherein a plurality of contrast degrees between respective magnetization of individual phases, 3) measuring the total macroscopic magnetization in a third magnetic field region on an NMR measurement segment, and 4) reading the multidimensional data matrix with a tangible computer readable medium.
