Introduction Fluidization is a process where a granular material is converted from a static solid-like state to a dynamic fluid-like state by passing up fluid through the granular material.
While high tangential velocity may lead to faster rate of material processing due to intense swirling, low pressure drop is important to ensure minimal power consumption.

The whole system was insulated with thermal insulation materials.
(2) According to the relation of heat transfer between internal tube and outer tube (cooling jacket), we can get (6) Where hi is heat transfer coefficient between gas-liquid flow and the internal side of tube, ho is heat transfer coefficient between cooling water and the outside of tube, λ is heat conductivity of tube material. di, do are internal and outside diameters of tube respectively.

Since in our material the influence of the dislocation network was much stronger - R was reduced by 4 orders of magnitude - we believe that this effect is related to enhancement of both, the electron concentration and the electron mobility.
