In a D300?mm jetting fluidized bed with a three-nozzle distributor, the voidage distribution was simulated by two fluid model combined with kinetic theory of granular flow.

The gas-solid fluid dynamic characteristics mainly including voidage distribution, pressure distribution, gas velocity and particle velocity, have deep influence upon combustion, heat transfer, pollutant formation and control in the Circulating Fluidized Bed (CFB) boiler and they also affect the stability and economy of the equipment performance.

Impact of porosity on the performances of asphalt pavement;

The relationship between average void ratio of catalyst flowing and superficial speed of steam in stripper's external annular space was deducted and the result of experimental analysis showed that data achieved in experiments were in agreement with the relationship.

Five sizes of coarse aggregate and void ratios were adopted.

Then it represents the direct relation between the water damage and the void ratio in field,and points out only controlling void ratio in field strictly,the construction quality can be increased and the water damages can be reduced.
