- •
A dynamic model of ash deposit formation was developed by DSMC method.
- •
The deposit thickness of the inner layer is less than that of the outer layer.
- •
The ash deposit thickness increases by 47.52% with the load increases by 20%.
- •
Results are consistent with the morphology of ash deposit determined by SEM/EDS.
