Abstract

  1. The diffusion terms in the mean velocity and temperature equations of turbulent flow are analysed to decide when variations of fluid properties can produce appreciable errors.

  2. A theoretical demonstration is given that in the mean-flow continuity equation for a gas the error in assuming constant density is small if the flow is turbulent, even when the temperature variations are large.

  3. Separate discussion is given of the case of local heat sources in turbulence, as large errors can occur there.
