SOME SYSTEMATIC MISTAKES IN NEAR-WALL TURBULENCE MODELING AND POSSIBLE WAY TO OVERCOME THEM

Boris Golovnya

Abstract


All near-wall models of turbulence do not reproduce the cascade energy transfer. In the author opinion, models poorly take into account the structure of near-wall turbulence. Therefore these models can not reproduce correctly all processes in turbulent boundary layer. Traditional correction terms can not be regarded as physically reasonable solution of the problem. As a result there are many turbulent flows that can not be simulated. This paper presents a possible explanation of difficulties encountered in the development of turbulence models for the calculation of the boundary layer. A technique to overcome these difficulties is presented.


Keywords


turbulent boundary layer, near-wall turbulence modeling.
