Bubbling fluidization has been widely applied in process industries, such as power generation from coal, renewable energy production, gasification and pyrolysis. In this study, we attempted to predict solid flow patterns, solid and gas mixing, bubble behaviour in a bubbling fluidized bed based on operational conditions and bed design.
A ‘Flow Pattern Parameter (FPP)’ has been proposed to identify the solid flow pattern in a bubbling fluidized bed.
The ‘Flow Pattern Parameter (FPP)’ consists of particle kinetic energy, bed aspect ratio (H/D), pore size of air distributor, minimum fluidization velocity, and superficial gas velocity. The results show that solid flow patterns in the bubbling fluidized bed can be clearly classified based on the Flow Pattern Parameter. Different flow pattern corresponds to a certain range of the Flow Pattern Parameter.
