摘      要：Thermophysical analysis of the crustal rocks is important for heat transfer determination and insulation purposes to save energy in *** the presented work,thermophysical properties of four limestones were investigated in dry and moist state under ambient conditions by using a transient plane source method.A thermal constant analyzer was used to raise the sample temperature and to measure the thermal properties in the temperature range of 300 K to 433 *** conductivity and diffusivity were measured by developing a linear relationship between temperature response of TPS (transient plane source) sensor and dimensionless time function through least-square fitting *** experimental observations and predicted thermal conductivity of samples have shown that in-situ observations are important to determine the thermal properties *** effect of temperature on thermal properties of limestone was defined by considering the chemical composition of the samples and associated heat transfer *** thermal conductivity and diffusivity of limestone decreased while specific heat capacity increased with a rise in *** overall findings indicate that the spinoff of this research is useful in studying the reliance of thermophysical properties of rocks on their structures and lithology.
