## EXPERIMENTAL STUDY OF THE EFFECT OF PH VALUE ON MELTING RATE OF ICE

• 摘要: 冬季积雪、深部软岩巷道流变、高原冻土翻浆等现象给我们的日常生活和工程建设带来了极大的不便,这些现象都涉及到固体与流体之间的转化现象,因此材料固流转化理论研究具有重要的理论意义和应用价值.本文以酸碱度为自变量,通过冰块融化实验,研究了其对融冰速率的影响,结果显示,随着pH值的增加,冰的融化速率有先变慢后加快的趋势.通过数据分析,得出了酸碱度与融冰速率关系的经验公式,并用Fluent进行了数值仿真验证.

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.
