THEORY AND CONSTANTS OF WALL TURBULENCE
01.00.00 Physicalmathematical sciences
DescriptionThe completely closed model of wall turbulence was derived directly from the NavierStokes equation. The fundamental constants of wall turbulence including the Karman constant have been calculated within a theory. This model has been developed also for the accelerated and nonisothermal turbulent boundary layer flows. The estimated mean velocity, temperature and impurity concentration profiles as well as the spectral characteristics of the streamwise velocity component are to be shown in a good agreement with the experimental data

TURBULENCE THEORY AND ROUGHNESS DENSITY EFFECT MODEL
01.00.00 Physicalmathematical sciences
DescriptionThe model of the turbulent boundary layer over a rough surface is presented. The model is based on the special type of transformation of the NavierStokes equation. The turbulent boundary layer in this model is considered as a flow above the rough surface generated by the viscous sublayer (the dynamic roughness effect). The roughness density effect on the shift of the mean velocity logarithmic profile has been estimated in the case of 2D and 3D roughness elements
