Abstract

Heat transfer experimental results obtained using thermochromic liquid crystals and data processing and their comparison with numerical predictions J. Stasiek*, M.W. Collins, M. Ciofalo**, P. Chew*** Thermo-Fluids Engineering Research Centre, City University, London EC1 V OHB, UK ABSTRACT Thermochromic Liquid Crystals (TLC) have significant potential for thermal measurements in industrial contexts. They are one of a number of new non-invasive whole field optically-based methods for thermofluid investigations. The experimental results lend themselves to automatic recording and fringe and data processing software and equipment available today. TLC can give real-time data, and are on an experimental par with the predictive potential of Computational Fluid Dynamics (CFD) and heat transfer. They form a powerful method, therefore, for code validation. In this paper, we carefully review the above issues, and use as an illustrative example our own work in applying
