다양한 함수비를 가진 화강암의 열전도도 추정을 위한 실험적 모델
Empirical model to estimate the thermal conductivity of granite with various water contents
Abstract
To obtain the input data for the design and long-term performance assessment of a high-level waste repository,the thermal conductivities of several granite rocks which were taken from the rock cores from the declined borehole were measured. The thermal conductivities of granite were measured under the different conditions of water content to investigate the effects of the water content on the thermal conductivity. A simple empirical correlation was proposed to predict the thermal conductivity of granite as a function of effective porosity and water content which can be measured with relative ease while neglecting the possible effects of mineralogy, structure and anisotropy. The correlation could predict the thermal conductivity of granite with the effective porosity below 2.7% from the KURT site with an estimated error below 10%.
