The accelerating rate calorimeter is a commonly used tool for evaluating thermal hazards. Due to the thermal inertia, the heat dissipation between the reaction system and the furnace, the pure adiabatic condition cannot be achieved. This leads to inaccurate thermodynamic and kinetic results. To systematically study and correct this heat dissipation, numerical simulations and experiments were carried out to investigate the main heat dissipation path and the factors. The results show that convection is the main heat dissipation pathway. The dynamic characteristics of the thermocouple and sidewall have different effects on reactions with different self-heating rates. In addition, a heat dissipation correction method based on the heat transfer model is proposed and validated by simulations and experiments. The simulation and experimental results both show the effectiveness of this correction method. These mean it has a certain significance for the improvement of the accelerating rate calorimeter experimental data processes.

加速量热实验样品的散热分析与校正

加速热量计是评估热危害的常用工具。由于热惯性、反应体系与炉体之间的散热，无法达到纯绝热条件。这导致热力学和动力学结果不准确。为了系统地研究和纠正这种散热现象，通过数值模拟和实验研究了主要的散热路径和影响因素。结果表明，对流是主要的散热途径。热电偶和侧壁的动态特性对不同自加热速率的反应有不同的影响。此外，提出了一种基于传热模型的散热校正方法，并通过仿真和实验进行了验证。仿真和实验结果均表明了该校正方法的有效性。这对于加速量热仪实验数据处理的改进具有一定的意义。
