Resumo

A method has been proposed and implemented for experimentally measuring the effective conductivity of a limited volume of a metal melt with an admixture of solid well-conducting particles depending on the volume fraction of the impurity in the range from zero to seven percent. A comparison is made with known theoretical dependencies for effective conductivity. It is shown that none of the considered models provides even qualitative agreement with experiment. On the experimental curve, several sections can be distinguished with different dependences of conductivity on the volume fraction of the impurity. The experimental data are approximated by analytical functions, which make it possible to use the results obtained for numerical modeling of MHD processes.
