DETERMINATION OF THE THERMAL CONDUCTIVITY IN SOLIDIFYING INGOTSV. K. Tolstykha and N. A. Volodinb UDC 536:681.51.015 The problem of identification of the effective thermal conductivity in a solidifying ingot is considered on the basis of experimental data. The possibility of its solution with identifiability conditions obtained and implemented in the present work is determined. aDonetsk National University, Donetsk, Ukraine; email: firstname.lastname@example.org; bDonetsk National Technical University, Donetsk, Ukraine.
