Experimental and theoretical studies have been performed for entrainment at T-junction consisting of hot leg and ADS-4 pipe. Research of basic influence factors on onset entrainment and stable entrainment is conducted and the effects of gas chamber height and gas Froude number on entrainment are discussed on the basis of experimental data. Based on visualization research, the flow regime in the main pipe is recorded by high-speed camera. Three kinds of entrainment phenomena including stratified entrainment, annular entrainment and intermittent entrainment can be clearly found, and feature of each phenomenon is summarized. Also, Onset entrainment model is established and accords with experimental data well.
