Magnetic Resonance Imaging is used here to study four phenomena: two-phase water/oil flow in porous media, rheology of fiber suspensions, natural convection in complex fluids and water diffusion in polymer membranes. These studies required the use or development of appropriate devices to maintain controlled external conditions in terms of mechanical stress, temperature or humidity. This article focuses on the instrumentation and methods used to perform MRI measurements on these systems. RÉSUMÉ :L'Imagerie par Résonance Magnétique est utilisée ici pour l'étude de quatre phénomènes: l'écoulement diphasique eau/huile dans des milieux poreux modèles, le cisaillement de suspensions de fibres, la convection dans des fluides complexes et la diffusion de l'eau dans des membranes polymères. Ces études ont nécessité l'utilisation ou le développement de dispositifs adaptés, permettant de maintenir des conditions externes contrôlées en termes de contrainte mécanique, température ou hygrométrie. Cet article met l'accent sur l'instrumentation et les méthodes mises en oeuvre pour mener à bien des mesures d'IRM sur ces systèmes.

“…These latter techniques restrict the setup to transparent walls in order to make possible the flow visualizations. The MRT technique (Magnetic Resonance Thermometry) is widespread in the medical field (see reviews [3,4,5]). In this field, MRT is principally performed in vivo on systems at rest (without fluid motion).…”

“…Indeed, different MR parameters show a sensitivity to the temperature. Several NMR (Nuclear Magnetic Resonance) techniques may evaluate the thermo-dependency of a fluid [3,4,5] : (i) The material sensitivity to the temperature can be evaluated by considering the Proton Resonance Frequency (PRF). The temperature fields can be obtained by measuring the phase difference due to the resonance frequency variation occuring when the temperature is modified [10,11,12,13].…”

Experiments in Fluids, Springer Verlag (Germany), 2018, 59 (2), 10.1007/s00348-018-2494-3. hal-01693075Noname manuscript No. Résumé Magnetic Resonance Thermometry (MRT) is an innovative technique which can provide 2D and 3D temperature measurements using Magnetic Resonance Imaging (MRI). Despite the powerful advantages of MRT, this technique is sparcely developed and used in the engineering sciences. In this paper, we investigate the possibility to measure temperatures with MRI in a fluid layer submitted to heat transfer. By imposing a vertical temperature gradient, we study the temperature fields in both conductive and convective regimes. The temperature fields are obtained by measuring the transverse relaxation time T 2 in glycerol, a Newtonian fluid. The MRT protocol is described in detail and the results are presented. We show that for a conductive regime, temperature measurements are in very good agreement with the theoretical profile. In the convective regime, when comparing the temperature and velocity fields obtained by MRI, we get an excellent agreement in terms of flow structure. Temperature uncertainties are found to be less than 1• C for all our results.
