- •
A 2.5D model is applied to simulate the gas–solids flow in CFB riser.
- •
An important parameter in 2.5D model determines the shape of 2.5D geometry.
- •
The effects of this parameter on the hydrodynamics are comprehensively investigated.
- •
Careful comparison of 2.5D and 2D simulation results against experimental data
- •
2.5D model gives better agreement with experimental observations.
