摘要

在非差示量热计中,环境温度、恒温器温度和恒温器冷却系统都会影响测得的热流密度。因此,建模和校准程序应考虑到影响通过量热计传递的热通量的所有变量。在这项工作中,我们提出了三个非差分皮肤量热计的完整校准,旨在测量局部皮肤表面的热流密度,热容量和热阻。此外,将皮肤结合到量热模型中,可以确定进行测量的组织的核心温度。电校准是通过测量一个30岁健康男性受试者手腕掌侧和背侧的三个热量计来验证的。

Modelling of heat conduction calorimeters. Case of a non-differential skin calorimeter
In non-differential calorimeters, the ambient temperature, the thermostat temperature, and the thermostat cooling system affect the measured heat flux. For this reason, the modelling and calibration procedures should take into account all the variables that affect the heat flux transmitted through the calorimeter. In this work, we present the complete calibration of three non-differential skin calorimeters designed to measure the heat flux, the heat capacity and the thermal resistance of a localized skin surface. In addition, the incorporation of the skin into the calorimetric model allows the determination of the core temperature of the tissue where the measurement is performed. The electrical calibration is validated with measurements with the three calorimeters on the volar and dorsal areas of the wrist of a healthy 30-year-old male subject.

期刊介绍: Thermochimica Acta publishes original research contributions covering all aspects of thermoanalytical and calorimetric methods and their application to experimental chemistry, physics, biology and engineering. The journal aims to span the whole range from fundamental research to practical application. The journal focuses on the research that advances physical and analytical science of thermal phenomena. Therefore, the manuscripts are expected to provide important insights into the thermal phenomena studied or to propose significant improvements of analytical or computational techniques employed in thermal studies. Manuscripts that report the results of routine thermal measurements are not suitable for publication in Thermochimica Acta. The journal particularly welcomes papers from newly emerging areas as well as from the traditional strength areas: - New and improved instrumentation and methods - Thermal properties and behavior of materials - Kinetics of thermally stimulated processes
