摘要
电子计算机辅助红外断层摄影技术,是一项把红外测试技术应用于加热设备内壁热场分布检测的高新技术。加热设备内部热场的变化,由于热传导必然反映到设备外部,用热像仪可测出表面温度分布热图,已知表面温度值求解系统的几何形状,是热传导问题的一种反运算。本文详细地介绍了应用电子计算机求解这类反问题的一种通用解法,最后简述了提高计算精度的途径。
Infrared computerized axial tomography is a high technology for the application of IR testing in measuring temperature distribution in the inner- wall of a heating equipment. The temperature changes in the inner part of the heating equipment must be appeared onto the outter surface because of heat conduction. The surface temperature distribution can be abtained by thermal imager. With the known value of the surface temperature, to make a solution of system geometries is an inverse heat conduction problem. This paper describes in detail a general method for the solution of inverse heat conduction problems by computer and presents briefly a way to obtain better calculation accuracy.
