The aim of the paper is to describe a new, rapid transient method for the determination of thermal diffusivity and thermal conductivity of rocks. The present transient method is based on the application of a constant heat flux to the top surface of a block of rock that is insulated on all other surfaces. Results of a sensitivity analysis of the method indicate that thermal diffusivity can be measured to a best accuracy of about 3 percent, and thermal conductivity of saturated rocks can be determined to a best accuracy of about 8 percent. The method provides estimates of thermal conductivity that are consistent with estimates made using the steady‐state divided‐bar apparatus. The method is applied to determine the thermal conductivity of a suite of rocks from western Australian sedimentary basins.

Ground source heat pump (GSHP) is an effective energy saving technology for heating and air conditioning. Thermal conductivity of soil is a critical parameter for designing a GSHP system, as the parameter is indispensable in analyzing and determining initial investment, energy saving effects, and operating performance of the system. In this study, the major influencing factors of soil thermal conductivity were analyzed. With different compositions and water contents of soil, the values of conductivity were determined experimentally, which can provide essential data for designing a GSHP system.

Property Measurement

New transient solutions are derived for the simple calculation of thermal conductivity, specific heat, thermal diffusivity and contact conductance from the results of a single experiment. All the proposed experiments utilize a specimen which has one surface insulated and the opposite one heated by an arbitrary heat flux. The heat flux must have a finite duration and its integrated value must be known. Two types of experiments are discussed and measurements for each type are given. One type uses a flat, thin electric heater and the other uses a material of known specific heat as a calorimeter. Relative advantages are discussed.

The paper introduced a new-style vitrified micro bubbles aerated concrete block. By adding a certain amount of vitrified micro bubbles to general aerated concrete, the compressive and breaking strength can reach the B05 self-insulation standard. And the thermal conductivity of single new-style aerated concrete wall can realize the target of energy saving. It is proved that vitrified micro bubbles aerated concrete is a new wall material with the functions of containment, energy saving, sound insulation and self-supporting.
