Infrared Techniques for the Evaluation of Silicon Carbide Heat-Exchanger Tubing
The potential application of infrared techniques to detect flaws and measure heat transport in silicon carbide heat-exchanger tubing is discussed. Axial heat-flow patterns were monitored with a commercially available infrared camera. Computer modeling was used to help establish the relationship between temperature distributions and the various thermal parameters. The experimental data and computer-modeling predictions were in fair agreement. These tests indicated that thermography may be a useful nondestructive-evaluation technique for rapid assessment of thermal-heat-transport properties in silicon carbide heat-exchanger tubing.
