摘要：
Multiphase reactors are most widely encountered in chemical, metallurgical, energy and pharmaceutical industries. Because multiphase flow in reactors is generally unstable, nonlinear and non-equilibrium in nature, many challenges are exerted to multiphase flow detection technology. It has always been one of the frontier studies in process engineering to accurately measure and comprehend multiphase hydrodynamics, as well as to discover and master rules for design and scale-up of multiphase reactors. Magnetic resonance image (MRI) technology, an advanced non-invasive detection method, can obtain accurate and detail information of multi-dimensional transient fields, such as transient solid concentrations, velocity (fluctuating) fields, flow pattern recognition, bubble vortex structure, particle clustering, and meso-scale heterogeneous structures. Additionally, MRI could have good prospective applications for validation and improvement of numerical models. This review discussed MRI principle, analyzed current status of MRI application for gas-solid and gas-liquid flow hydrodynamics, and prospected promising future directions. © All Right Reserved.
