Improvement on the plane-source method with constant heating rate on the boundary

Cui Ping et al (Dept. of Air Conditioning Engineering, Shandong Institute of Architecture and Engineering, Jinan 250014, China)  
The problem of transient heat conduction in a semi infinite medium with the heat capacity of the heater on the boundary considered has been solved analytically . On this basis a new data processing method is presented, and the traditional plane source method is revised for measuring the thermal conductivity and diffusivity of insulating materials. Compared with the traditional plane source method the improved approach can obtain more accurate teste results in virtue of eliminating the system error caused by the heat capacity of the heater.
