A three dimensional transient model is developed to simulate the local hydrodynamics of a gas–liquid–solid three-phase fluidised bed reactor using the computational fluid dynamics (CFD) method. The CFD simulation predictions are compared with the experimental data of Kiared et al. [1999. Mean and turbulent particle velocity in the fully developed region of a three-phase fluidized bed. Chemical Engineering...
Flow regime boundaries and pressure drop in trickle bed reactors are crucial for design, scale-up and operation of such reactors. The flow map experiments are performed in a pilot plant reactor of 0.051m diameter and 1.2m height, with cumene–hydrogen system. A new technique – the acoustic signal measurement – is used for distinguishing between trickle and pulse flow regimes. The effect of operating...
