Emergent Behavior in a Low-Order Fluidized-Bed Bubble Model

Low-order models are becoming increasingly useful for simulating the complex collective behavior arising in large dynamical systems. Modeling of traffic flow and the behavior of biological systems such as ant colonies and bird flocks are commonly referenced examples of this new approach. We have explored the application of this type of model to describe the dynamics of voids in bubbling fluidiz...

Experimental Study of Effects of Particle Size Distribution on Bubble Behavior for Validation of Cfd Modeling of Bubbling Fluidized Bed

The efficiency of fluidized bed reactors depends on bubble distribution, bubble size and bubble velocity within the reactor. The sizes and size distributions of particles used in the bed may lead to different bubble behaviour. The objective of this work is to study the influence of particle size distribution on bubble behaviour. The results from the experiments will be used for validation of CF...

vibration effect on particle bed aerodynamic behavior and thermal performance of black tea in fluidized bed dryers

black tea sample was dried by a vibro-fluidized bed dryer to find its aerodynamic behavior and thermal performance during drying. the drying experiments were conducted at three different inlet air temperatures of 100, 115 and 130°c and fluidization condition at five vibration intensity levels of 0 (no vibration), 0.063, 0.189, 0.395 and 1.184. the results showed that bed channeling and defluidi...

Bubble formation on a single orifice in a gas solid fluidized bed using digital image analysis

Digital Image Analysis (DIA) has been employed to characterize the time evolution of a bubble injected from a single orifice into a pseudo 2-dimansional gas-solid fluidized bed. The injected bubble diameter increased with the square root of time before detachment. During bubble free flight in the bed, its diameter remains approximately constant. The center of mass of the bubble increases with t...

Particle Development in a Fluidized Bed Black Liquor Steam Reformer

Low-temperature gasification of black liquor is a new alternative to the conventional Tomlinson recovery boiler for recovering pulping chemicals and energy from black liquor in pulp and paper mills. This process can be carried out in a fluidized bed based on steam reforming at 600 C using indirect heat supplied via heat exchangers built into the fluid bed. As black liquor is injected into the b...
