- •
A numerical model of particle deposition was developed for predicting particle deposition rate on fin surface of heat exchanger.
- •
The transformation criterion was proposed to switch the impact type from particle-wall impact to particle-fouling layer impact.
- •
Both the sticking criterions and removal criterions were established for the incident particles and bed particles respectively.
- •
The particle distributions on fin surface predicted by the model agree well with the images captured in the visualization experiment.
