Numerical investigation of heavy fuel droplet-particle collisions in the injection zone of a Fluid Catalytic Cracking reactor, Part I: Numerical model and 2D simulations
Simulation of droplet-particle collisions using 2D CFD two-phase flow model. Evaporation and surface reactions (2-lump scheme) are taken into account. Parametric investigation on drop size, impact velocity and particle temperature. Gasoil conversion levels are predicted for parametric collision scenarios. Drop levitation predicted on hot particles thus avoiding solid-liquid contact.
