Abstract

Paper is devoted to the measurement of thermal conductivity for metals. Heat transfer inside the metallic bar is realized by heating the bar at one side and cooling it at another one by the mixture of water and ice. Input power to the heater and temperature at two points are measured at the bar. Heat losses are compensated by the measurement of dissipated power needed for the heating of heater itself to the same temperature as during the heat transport through the bar. Experimental results are presented for the brass, steel and aluminum bar and their thermal conductivities are measured.
