Contribution to the Modelling of Near-Wall Turbulence

The paper considers the modelling, within the framework of second-moment closure, of the turbulent stress field in the wall-adjacent sublayer. Particular attention is given to handling wall-proximity effects on the pressure-strain (o ij ) and stress-dissipation (e ij ) processes. Comparisons of the resultant model with the direct numerical simulations of plane channel flow show close agreement of the Reynolds stress profiles at two Reynolds numbers.
