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