An Experimental Study on Sea Water Freezing Behavior Along Horizontal Cooled Cylinder With Bubbly Flow

기포를 동반한 유동장에서의 냉각원과 주위의 해수동결에 관한 실험적 연구

This study was experimentally performed to investigate freezing behavior of sea water along horizontal cooled a circular tube with bubbly flow. The experiments were carried out for a variety of parameter, such as sea water velocity, air-bubble flow rate, and cooled-tube temperature. The shape of freezing layer, freezing rate and salinity of frozen layer were observed and measured. And the flow patterns around cooled tube were visualized using the PIV to analyze the relationship between the flow structure and the freezing characteristics. It was found that the experimental parameters gave a great influence on the freezing rate and the salinity of the frozen layer.
