文摘

A theoretical framework with an inertia-based multi-spray interaction is developed. Spray model with individual spray properties and feeding operations is developed. A model to calculate radial transport of both gas and solid phases is derived. The inlet condition of catalysts asymmetric feeding is correlated by CFD simulation. Significant difference can be obtained by adjusting asymmetric feedings.
