EQUIVALENT THERMAL CONDUCTIVITY IN CYLINDRICAL VOLUME WITH SOLUTION

Abstract

The results of experimental determination of the equivalent coefficient of thermal conductivity by the method of regular thermal regime in a confined space for the system "water-wall-viscous liquid" are given in the paper. The obtained results are compared with the results of experimental and analytical studies of well-known authors. The hypothetical distribution of circulating circuits in the experimental installation is given. The conditions of leakage of the heat exchange process during the experiment are described, possible factors which lead to errors and their influence on the obtained results.

It is proved that, depending on the scheme of heat exchange processes, the experimental coefficients of thermal conductivity in the cylindrical volume have higher values than those calculated in the slot channels.
