Question

why minimum fluidization velocity is important to calculate

Answer 1

The minimum fluidization velocity is one of the most important parameters that define the fluid-dynamic characteristics of a fluidized bed(Fluidized bed is physical phenomenon occurring when quantity of a solid particulate substance is placed under appreciate condition to cause a solid/fluid mixture to behave like fluid) . Not only does this parameter quantitatively indicate the drag force that is required for the suspension of a solid in the gaseous phase, it also constitutes a reference for evaluating the intensity of the fluidization regime when using high velocities.
