Abstract

Thermal properties of liquids, especially thermal conductivity, are important issues in the designing, developing and application of products. In this paper, the method of thermal conductivity determination is based on heat transfer process analysis during transient phenomena caused by an energy pulse, with application of parameter value estimation of process model. Essentially, influence of energy pulse on the liquid condition in the measuring cell is negligible.
