摘要：

Experiments on and numerical simulation of a swirl fluid catalytic cracking (FCC) feed nozzle were presented. In the experiments, the spray angle and sauter mean droplet (SMD) were measured at different flow rates. Then pressure drop on each section of nozzle was verified. Volume of Fluid (VOF) method was used to simulate the gas-liquid flow process in a swirl FCC feed nozzle. The simulation exhibited the process of two-phase flow filling feed nozzle. The nozzle pressure, velocity distribution and spray angle were calculated; the calculated results agreed well with validated by experimental data. The results show that: the SMD size of feed nozzle is 53-60 μm; the spray angle increases with increasing gas/liquid mass ratio or flow rate; the spray pattern is fairly evenly distributed within combined cyclone. ©, 2015, Xibei Gongye Daxue Xuebao/Journal of Northwestern Polytechnical University.
