Research on Film Insulation Technology for Artificial, Open Water Delivery Canals Based on Solar Heat Radiation Utilization

A measure of insulation film floating on the water surface was put forward to solve problems ice damage delivery canals during winter operation period in cold regions. Firstly, a circulating flume test system designed an indoor radiation- and temperature-controlled environment. Secondly, five groups comparative tests were carried out according different application scenarios. Lastly, combined with experimental data, radiative degree-day method used calculate thickness growth under film. The results show that, sufficient radiation condition, membrane can effectively melt canal prevent formation. In limited delay sealing time reduce thickness, avoiding thrust lining. formula predict development process this technique. research provides certain theoretical guidance practical significance for combination solar thermal technology engineering
