Abstract
Under thermal shock, the heat conduction between granite and fluid will lead to the redistribution of rock temperature field, while indoor thermal shock test cannot determine the distribution rule of temperature field inside granite accurately. In order to explore the influence of fluid velocity on the thermal shock process of granite, the temperature field and flow field is numerically simulated by COMSOL. The results show that heat transfer between granite and fluid is in the form of waves. In the process of heat conduction, the internal temperature and heat balance time of granite are greater than those of rock surface. The time of heat balance in rock provides reference for the design of indoor thermal shock test. After thermal shock, the temperature of granite is lower than the initial temperature. With the increase of fluid velocity, the thermal equilibrium time of granite decreases, and the final rock stable temperature decreases. According to the relationship between velocity and granite temperature, a linear correlation model between velocity and maximum instantaneous thermal shock velocity is proposed. It is also verified that the thermal fluid–solid coupling model of granite under thermal shock is feasible to simulate the heat conduction and temperature distribution in granite.
