Local Heat Transfer Measurements Using Liquid Crystal Thermography Technique

Article Preview

Abstract:

The micro-encapsulated thermochromic liquid crystal has been used for the surface temperature measurement using its color change with heat. There are exciting new opportunities to apply this liquid crystal to the investigation of important and interesting heat transfer/fluid flow problems. The various techniques of using liquid crystal for the measurement of the local Nusselt numbers in very complex geometries are presented in this paper.
