| Popis: | We show the existence of a wall term in the equation for «u1u2» in a three-parameter model of turbulence by analogy with the known terms in an “E-e” model. We suggest a convenient system of differential equations for the boundary layer on a flat plate in fluid flow at small Reynolds numberse. We find the limiting calculated value of the turbulent Reynolds number at which wall terms must be taken into consideration. |
