The Experimental Study The Impact Of Ph And Pressure To Ice Melting Rate

The phenomena such as winter snow, rheology of deep soft rock roadway andboiling of plateau permafrost bring great inconvenience to our daily lives and theconstruction, so the theory of solid material flow conversion has important theoreticalsignificance and application value. There are so many materials, so many disciplinesare involved to the theory. This paper elaborates the process of the transformationbetween solid and liquid, and introduces the mechanism of the transformationphenomenon between ice and water. The phenomenon of ice melting is accompaniedby the occurrence of phase transitions, so the article describes the heat transfer theoryof phase transitions and ice melting model, deriving differential equations of heatconduction.In this paper, the melting experiments of ice which are formed from different PHsolution were done in the state of constant temperature. It is found that the stronger ofthe acid, the faster of the ice melting rate is. However, the melting rate of ice formedby alkaline solution decreases. When the solubility of sodium hydroxide increases to acertain extent, the melting rate will increase. The conclusion is obtained in the casethat the PH of the dilute hydrochloric acid or sodium hydroxide solution are between1to14. From the experiment study of ice melting rate under different pressure loads, wefound that as the load increases, the ice melting rate also tends to increase. But when itis up to a certain extent, this trend will level off, which also consistent with the actualnatural phenomenon. This paper curve fit the experimental data by using MATLAB,and obtained the empirical formula suitable for the scope of this experiment.Finally, simulate the process of ice melting based on the software FLUENT, andexamining the liquid rate of ice along with time. The results show that simulationprocess fit well with the actual experiment. This was validated against theexperimental conclusion.
