中医隔物灸的传热学研究

Heat Transfer Research in Traditional Chinese Indirect Moxibustion

运用有限元软件ANSYS进行数值建模模拟中医隔物灸产生的热在人体组织中的传导过程,并给出定性和定量分析。同时运用高灵敏度红外热像仪记录艾炷隔附子饼灸对生物组织热作用的过程,对比实验和计算结果验证了实验和数值模拟方法的合理性。然后建立简化的人体两维模型,得到穴位点横截面上热传导过程的两维温度分布图和热在生物组织中传播的整个过程。红外热像技术和数值建模方法为临床各种灸法的运用提供了理论和实验基础支持。

In this article, a mathematical model with the finite element analysis software ANSYS is established to simulate the heat transfer process in the human body during the Chinese tradition indirect Moxibustion. Qualitative and quantitative analysis of the heat transfer in the tissues are also done. At the same time, a high sensitive ThermaCAMTM infrared thermal imaging system is used to observe the infrared thermography during the whole moxibustion process. At first, we do experiments on the swine crura of indirect monkshood moxibustion. The comparison between the experimental results and the numerical ones verify the feasibility of the method. Then a 2 - D human model is established to analyze the heat transfer in the acupuncture cross -section and we get the temperature distribution in the whole tissue. Results reveal that the infrared thermography and the numerical simulation can be theoretical and experimental support in the research of all kinds of clinical moxibustion.
