Abstract
The effect of ionizing collisions on thermal conductivity λ is studied. A formal expression is obtained for λ with additional terms considering the presence of ionizing collisions in the gas. Calculations performed at p=1 atm and a temperature range of 10,000–25,000 °K show that the effect of ionizing collisions on translational heat capacity is not great. On the other hand, the presence of such collisions in the gas leads to a retardation of diffusion processes, which in turn leads to a significant reduction in the chemical component of the coefficient λ, with this reduction being strongly dependent on the choice of number of excited atomic levels realized in the gas.
