Modelling of turbulent flow in the near-wall region using PDF method

Marta Wacławczyk, Jacek Pozorski
The paper presents near-wall turbulence models which incorporate the idea of elliptic relaxation. The simplified elliptic blending model is applied in the Lagrangian probability density function (PDF) approach. The PDF method is extended to compute near-wall viscous momentum transport. Computations are performed for fully developed turbulent channel flow and validated against available DNS data.
