Screening wall effects of a thin fluidized bed by near-infrared imaging

This step-innovation introduces, for the first time, 2D mapping by NIR imaging to visualize flow dynamics inside gas-solid fluidized beds of low aspect ratios which have seen growing applications in pharmaceutical industry, thermo-gravimetric analysis and micro-fluidics owing to efficient mixing and affordable costs. Compared with conventional techniques (i.e. X-ray or neutron/gamma and MRI imaging), this prototype is species sensitive. This work initiated further developments on 3D optical tomography, was developed by a multidisciplinary international collaboration between chemists and engineers (UK and Japan), sponsored by DEL (Northern Ireland), shortlisted for oral talks (i.e. http://www.camure.org/sciprog.html) and reviewed for a book chapter (http://www.eurekaselect.com/101458/chapter/flow-visualization-in-gas-solid-packed-beds-by-spatially-resolved-near-infrared-imaging)
