Abstract
This work demonstrates that it is possible, and with relative ease, to determine unique characteristic temperatures for the red & green light intensity signals of a narrowband thermochromic liquid crystal mixture. It is proposed to utilize additional indicators in future transient thermochromic liquid crystals measurements to increase data throughput, improve robustness, and reduce uncertainty in the calculated heat transfer coefficient. Potential algorithmic implementations for a multi-color technique are discussed. Optimum conditions for minimizing the uncertainty in the calculated heat transfer coefficient are discussed and compared to that of the traditional single-color technique. The multi-color technique is also extendable to multi-band techniques.
