Abstract

Abstract

In order to quantitatively explore the main factors that affect the lateral melting of the ice layer and simplify the parametric scheme of the lateral melting rate of the ice layer, the melting process of pure water ice under the conditions of no wind, still water, no radiation and pure thermodynamics was simulated in the laboratory, the lateral melting amount of the ice layer was measured, and the laboratory air temperature, ice skin temperature, water temperature, ice temperature and other factors during melting were recorded. The observation results show that under the pure thermodynamic condition of no radiation, the ice layer melts uniformly in the lateral, and the melting rate of the upper and lower layers is faster than that of the middle layer. The results of correlation analysis show that there is a good linear correlation between air temperature and water temperature, ice temperature and ice skin temperature. Information flow results show that air temperature is the most important factor affecting the lateral melting of ice. Finally, a parametric model between the lateral melting rate and the air temperature is established by fitting, and is compared with previous parametric schemes. The results show that the parametric model in this study has a better simulation effect, and the standard deviation is the smallest, which is 0.08 mm/h, thus achieving the purpose of simplifying the parameters.
