Study and Application on the Gas-liquid Two-phase Flow in Micro-rectangular Pipe

Liquid and gas two-phase flow technology is the key problem of the cooling system design for evaporative cooling generator. It is presented that the characters of liquid and gas two-phase flow in the pipeline of which the size is close to the stator bar. From the two aspects, phenomenological model and empirical correlation, presents its development in micro -rectangle pipelines and the existent problems. It was also put forward some new study points. The achievement and prospective of evaporative cooling generator in China are stated.
