Abstract:

The coefficient of thermal conductivity of cesium vapor in the temperature range of 1600-2400K and the pressure of 15 mm Hg are measured. In the region of 1000-1600K, the results do not depend on pressure, but there is a sharp growth of the coefficient of thermal conductivity observed caused by the ionization heat transfer depending on pressure. This excess ionization coefficient of thermal conductivity depends on the coefficient of ambipolar diffusion of ions and electrons and also depends on the degree of ionization and consequently on pressure. The coefficient of thermal conductivity of argon, neon and mercury vapor in the range of 1100-2200K were measured in the process of mastering the experimental method.
