Two phase flow instability is a common phenomenon in many applications such as nuclear reactor, boiler, heat exchanger, chemical reactor, etc. Flow instability will cause mechanical vibration, which may bring about the local heat transfer deterioration. But for the gas-liquid reactor, the mechanical vibration caused by flow instability will strengthen the destabilization and increase the mass transfer at the gas-liquid interface. Therefore, the mass transfer will be enhanced. Such as in nuclear reactor, we need increase the mass transfer of boron. Currently, few studies did the researches on the mechanism of mass transfer enhancement and regular pattern of interface phenomenon caused by two phase flow instability. This paper deals with the problems in improving the mass transfer at two phase interface, studies the effects of flow pattern on the transfer characteristics and the influence of bubble’s growth and aggregation on the mass flow rate and outlet pressure. The mechanism and the regular pattern of interface destabilization are analyzed. The results reveal that the two phase instability has significant effects on the mass transfer through the interface.
