Assessment of the Dimensionless Groups-Based Scale-Up of Gas–Solid Fluidized Beds

The most common scale-up approach for gas–solids fluidized beds is based on matching the governing dimensionless parameters. In literature, this has been validated only by means of measuring global parameters between different sizes beds. However, such measurements are not sufficient to depict all interplaying hydrodynamic phenomena and hence verify relationships. Therefore, assess approach, an advanced optical probe pressure transducer measurement techniques have applied quantify local in two sized Four sets experimental conditions were designed conducted examine assessment scaling with matched mismatched groups results indicated that reported adequate achieving similarity terms solids holdup, gas particle velocity, mass flux, fluctuation. This finding demonstrates importance order evaluate Finally, further advance understanding present deeper insight into their dynamics.
