Methodology of Thermal Properties Measurement

conference paper

English

This paper deals with a methodology of temperature dependencies measurement of thermal properties. Specific heat and thermal conductivity are two thermal properties contained here. Thermal properties of each matter are dependent on their own temperature and are various in whole temperature range. Temperature dependencies of many commercial materials are well known. But temperature dependencies of biological tissues are very bad to find. However knowledge of these parameters is very important for the thermal processes computer simulation. .The methodology described here goes out of current methods deficiencies. Thermal conductivity of biological tissues is measured with the needle probe. This method has some deficiencies which are described in this paper. Specific heat is measured with Differential Scanning Calorimetry (DSC). The DSC is conventional method without serious deficiencies. Big disadvantage of current thermal properties measurement is in necessary using of both methods, i.e. two devices are used. Simultaneous measurement of thermal conductivity and specific heat is the main advantage of our methodology. Results of temperature dependencies measurement will be used in computer simulation for hypothermia cancer destroying.
