Abstract: The winter snow, the deep soft rock rheological deformation on the roadway and the frost boiling of the plateau permafrost all bring about great inconvenience to our life and the construction. These phenomena are related to the transformation between solid and fluid. Therefore, the theoretical study of materials transformation between solid and fluid have important theoretical significance and application value. In this paper, the pH value is taken as the independent variable, and its effect on the ice melting rate is studied through the ice cube melting experiment. It is shown that with the increase of the pH value, the melting rate of the ice will slow down firstly and then increase. An empirical formula is obtained, which can describe the relationship between the pH value and the ice melting rate. Finally, a simulation analysis is carried out by using Fluent.

Key words: transformation between solid and fluid|pH value|ice|melting rate
