Title
A Multi-Color Thermochromic Liquid Crystals Technique For Transient Heat Transfer Experiments
Abstract
This paper demonstrates a technique to obtain multiple independent measurements of surface temperature using a single band thermochromic liquid crystals mixture for improved accuracy over single surface measurement techniques. Detailed Nusselt number measurements were performed for a square, smooth-walled channel in the Reynolds number range of 50 000 to 150 000, based on channel hydraulic diameter, using the transient thermochromic liquid crystals technique. Heat transfer measurements were taken on all four walls so that the bulk temperature variation throughout the channel during the experiment can also be taken into account. Data are post processed using the traditional single color technique and compared to the new multicolor technique. The proposed multicolor technique can complement existing single color, multiband techniques without added complexity.
