A NEW FERROELECTRIC TRANSDUCER FOR USE IN HEAT TRANSFER AND FLOW STUDIES

Abstract

A transducer is described for the measurement of heat transfer rates in gaseous systems. Based on the ferroelectric properties of tri-glycine sulphate(CH2NH2COOH)3. H2SO4, the device autostabilizes its operating temperature so that external heat-transfer depends linearly upon the ambient temperature and the film coefficient. An analysis of temperature stability in several heat-sensitive transducers is presented, and the fundamental improvement in stability offered by the ferroelectric probe is demonstrated both in the analysis and experimentally. Data are presented in reference to possible applications of the device as a linear heat-transfer gauge and a binary gas analyzer. A qualitative discussion of transient response is given, and a comparison is made to a similar technique for the linear detection of diffusion- controlled processes in convected mass-transfer systems.
