Seminarium Zakładu Mechaniki i Fizyki PłynówSome applications of the NMR to the characterization of suspensions and two-phase flowsprof. Jacques Leblond, Ecole Superieure de Physique et de Chimie Industrielles, Paris, France |
Different uses of Pulsed Field Gradient Spin Echo - NMR sequences are presented to determine: - S(Q), the Structure Function and g(r), the pair probability distribution of a suspension of large spherical particules (100-600 um) in a viscous liquid; - the axial profile of the liquid fraction and of the velocity probability distribution of water in an intermittent air-water flow; - the fluctuations of the liquid mass flow and momentum in an air-water bubbly flow.
