| Abstract: | The principle of thermochromic liquid crystals thermography is described and thestandardization of relation between hue and temperature has been carried out. The technique has beenapplied to measure wall temperature distribution with a impinging jet. The wall temperature distributionin different impinging jet heigtht are given,as well as sensitivity and accuracy of the technology arediscussed. |
