Originální abstrakt
The paper deals with the application of multi-regression analysis for the determination of thermal parameters from transient responses to step wise heat power imput. The dependences of thermal diffusivity a, thermal conductivity, heat source quality parameter s, and heat losses parameter R on time were calculated from different parts of transient responses. The influence of the heat source fractal dimension D (determined from the heat source quality parameter s) on thermal parameters is discussed. The results correlate with the fractal model of heat transport. The dependences of thermal diffusivity on the fractal dimension of PCM differ from PMMA due to the phase change around the temperature 25 C.
