Computer Controlled Fluidization and Fluid Bed Heat Transfer Unit

When a current of fluid (gas or liquid) flows through a bed of particles, the growing friction between them and the fluid makes the particles of the bed, from a specific flow rate, be suspended in the fluid, not resting on one another. The bed takes a volume larger than the volume it has when that fluid does not flow. Under these conditions, it can be considered that a fluid bed has been formed, since the solid particles behave as the fluid particles, moving freely by gravity effect or being pumped. The main characteristic is that the temperature in every point of the bed is constant, due to the fact that heat transfer is very effective.
