Search for: [Abstract = "Most commercially available wall functions for k\-e turbulence models base on the two\-zonal near\-wall flowdivision assumption. Viscous and log\-law sublayers are distinguished. In this article the three\-zonal wall function conceptwith a buffer sublayer is developed. The aim of this new wall function is to improve the mean streamwise U\+ velocity profile.The proposed wall function is validated on backward\-facing step experimental data. Physical implications of the modelperformance are also discussed."]
