文摘
- •
A correlation developed to predict solids holdup in pneumatic conveying flow regime.
- •
Dimensionless quantities describing hydrodynamics of gas fluidised beds were used.
- •
Reduced solids flux phenomenon in risers was directly included in the correlation.
- •
The correlation predicted 90% of the experimental data with a mean deviation of 15%.
- •
The correlation is applicable for particle Reynolds numbers between 3.7 and 366.
