Thermophysical properties of different kinds of fish.

Author(s) : GHRAIZI J. A., ONISTCHENKO V. P., CHEPURNENKO V. P.

Summary

To design equipment and set specifications for freezing of fish and fish products, it is important to know with sufficient accuracy their thermophysical properties. The authors determined these properties for 25 species of fishes. Experimental data of various authors having errors of 3-7% in effective heat capacity, 3-5% in frozen-out water fraction, 1-3% in density and 5-10% in heat conductivity, are described. At negative temperatures the accuracy of the description depends sufficiently on the error in the frozen-out water fraction; the description of heat conductivity depends strongly on air impurities. Results of the work are accompanied by analytical expressions and illustrated by graphs, in which a comparison of the calculation and experimental data was made.
