A numerical study of laminarization effects in the turbulent boundary layers of accelerated flows
Abstract
A turbulence model is proposed which allows for the kinetic energy balance of turbulent motions and dissipation. Based on an analysis of experimental data, closed-form relationships are obtained for the equations of the turbulent boundary layer. The turbulent model is then used as a basis for developing a mathematical model of a boundary layer that is valid over a wide range of turbulent Reynolds numbers. By comparing calculations with experimental data, it is shown that the method proposed here provides an adequate description of laminarization effects in the turbulent boundary layers of accelerated flows.
