Some estimates of the diffusion stress tensor and the diffusion energy for a binary mixture of water vapour and dry air

The diffusion stress tensor and the diffusion energy cause significant difficulties with their evaluation and physical interpretation. In this paper, an attempt of estimation of diffusion stress tensor and energy of diffusion in case of binary mixture of dry air and water vapour was made. There will be pointed out that their numerical value is negligible low in comparison with order of partial stress tensor and internal energy, respectively.
