摘　　要：Injection of gas-liquid sprays into gas-solid fluidized beds finds application in many industries.Effective mixing and distribution of liquid feed and solid bed material is paramount to ensure an efficient and profitable process.Despite its long-term use,the mechanism of liquid injection into gas-solid fluidized beds continues to raise questions and is only partially understood.This paper provides a thorough and up-to-date review of experimental and numerical investigations of gas-liquid sprays into gas-solid fluidized beds conducted over the past decades.Based on the surveyed literature,a phenomenological description of the prevalent mechanisms of gas-liquid injection under different operating conditions is presented.This review identifies suitable computational fluid dynamic models for simulating the mechanisms involved in gas-liquid-solid interactions along with recommendations for future numer-ical and experimental work.
