Pressure Loss in Fixed, Fluidized, and Entrained Beds

2 Pressure Loss in Fixed, Fluidized, and Entrained Beds 

Pressure Drop in Fixed (Packed) Beds According to Ergun (1952), the pressure loss in a packed bed is given by  

For non-spherical particles we have to use an equivalent particle diameter defined 

Example 3.4.3 Influence of particle size on the pressure drop of a fixed bed 

Equations (3.4.24) and (3.4.21) lead to the following equation for the pressure drop of a fixed bed of spherical particles of equal size
