Thermal Characteristics of Concrete in the Vicinity of Embedded Cooling Water Pipe

This research is to reveal the thermal characteristics of concrete with the cooling water pipe. The temperature distribution is simulated by the finite element method, and an approximated method and a coupling method are used to analyze the concrete three-dimensional temperature field. The results of two methods show that the concrete temperature contours distribution in the vicinity of water pipe are similar, but the maximum temperature is different. The monitoring point temperature compared reasonably well at the same hydration time in these two methods, the coupling method temperature is larger than results of approximate method, and the maximum temperature difference is 0.9℃. The influence of cooling water on temperature distribution is achieved by loaded the convective heat transfer coefficient in approximate method, thus the coupling method results can be better quantitative analysis the concrete temperature distribution and the effect of the cooling water than approximate method. These results will provide a data support for study the concrete thermal field with cooling water pipe system.
