Detection of invisible heterogeneous flows in materials using a thermal-image technique and its model analysis
- Ibaraki Univ. (Japan). Faculty of Engineering
A thermal detection technique using an infrared radiometer is discussed and applied to the detection of internal heterogeneous spatial positions in materials. The internal heterogeneous space represents a cavity, an inclusion and a separation of materials. To maintain and manage various structures, their positions must be analyzed. Therefore, in this study, the transient temperature distribution above internal flaws was measured. Solar energy and lamp energy were used to realize nonsteady temperature fields on the surface of materials within an internal heterogeneous space and those temperature fields were estimated experimentally. Moreover, the authors certified the temperature field using the proposed model based on experimental results. The detection limit of the thermal detection technique is also discussed simultaneously.
