2V mf mf 149. the minimum fluidization velocity for a bed of particles...
Introduction:
The minimum fluidization velocity (Vmf) is the minimum velocity required for a bed of particles to achieve fluidization where the particles are suspended in the fluid. In this scenario, an increase in superficial gas velocity from Vmf to 2.5Vmf is considered.
No change in drag on particles:
An increase in superficial gas velocity does not affect the drag on particles. The drag force on particles is dependent on the particle size, shape, and density, as well as the fluid properties. The increase in superficial gas velocity does not change any of these factors, so there is no change in the drag on particles.
No change in drag on column walls:
Similarly, an increase in superficial gas velocity does not affect the drag on column walls. The drag force on column walls is dependent on the fluid properties, the height of the bed, and the shape of the column. The increase in superficial gas velocity does not change any of these factors, so there is no change in the drag on column walls.
No change in bed height:
An increase in superficial gas velocity does not affect the bed height. The bed height is dependent on the weight of the particles and the fluid velocity. The increase in superficial gas velocity does not change the weight of the particles or the fluid velocity, so there is no change in the bed height.
No change in bed voidage:
An increase in superficial gas velocity does affect the bed voidage. Bed voidage is the ratio of the volume of voids to the total volume of the bed. An increase in superficial gas velocity can cause the particles to expand and the voids to increase, which results in a decrease in bed voidage. However, the increase in superficial gas velocity is not enough to cause this expansion, so there is no change in the bed voidage.
Conclusion:
In summary, an increase in superficial gas velocity from Vmf to 2.5Vmf does not result in any change in the drag on particles, drag on column walls, bed height, or bed voidage.
