Characterization of a spherical heat source for measuring thermal conductivity and water content of ethanol and water mixtures

Abstract: Abstract. The study and the development of measuring methods of thermal conductivity are essential in several engineering applications, since as a consequence of the current justified demands on saving and rational use of thermal energy, the heat transfer with the maximum efficient as possible is of great relevance. The measurement of the water content is also a relevant parameter in several research areas and industrial sectors, since the quantity of water in the substances influences several biological, chem… Show more

“…To achieve the aim, the following objectives were set: -to substantiate the possibility of using the thermistor direct heating method to determine the thermal conductiv-termine the composition of gas mixtures in process mixtures of different composition [1] in gas analyzers with the aim of developing modern innovative cooling liquids (nano-liquids) [2], nondestructive testing of the binder liquid content in polymer-composite materials at the stage of their manufacture [3]. Also, the "thermal conductivity method" is used to measure the content of water and ethanol in mixtures [4], to determine the presence and degree of immunological reaction [5], to determine the surface heating temperature of an ultrasonic emitter [6], etc.…”

“…The author has conducted an experimental study, and the experimental results show that the average measurement error of LSSVM model is 0.542 % in the range of oil content from 8 % to 90 %, but there is no full range of moisture content value, this paper utilizes the principle of heat transfer to continue to measure water content over the full range 0–100 %. Brionizio, J D et al [ 9 ] conducted experimental and theoretical research on a method based on a spherical heat source to measure the thermal conductivity of liquids. The key research objects in this article are water, ethanol, Oil water mixture, and the determination of the water content of binary samples.…”

“…In Ref. [ 9 ] to be measured is the water content of water and ethanol, in this paper, with the help of reference [ 9 ] heat transfer method of measurement principle, the oil and water emulsification is mixed well for the measurement of water content. Klepikova, M [ 10 ] et al studied the potential of using thermal tracer testing to characterize shallow alluvial aquifers.…”
