The liquid crystal method for the visualization and measurement of heat transfer distributions
Abstract
The use of liquid crystals for heat transfer measurements is described. Properties of liquid crystals are discussed, with special emphasis on temperature resolution and adjustment time. Transient heat transfer measurements are dealt with and the experimental apparatus and procedure are presented. It is concluded that the possibility of measuring temperatures and temperature changes on the surface of models with the help of liquid crystals opens up new ways of performing heat transfer measurements in a relatively simple manner. Since the structural change of the liquid crystals is reversible, the experiments can be repeated several times.
