Study Notes

Fluid-Particle System Characteristics

Pressure drop in a fluid-particle system is related to the velocity of the system, as described by Ergun's equation.
In a packed bed state of spherical particles, the porosity of the bed is a key characteristic.
When water is used as the fluidising medium, the bed height in the fluidised state is a significant parameter.
