Using singlepoint velocity probability distributions for characterizing turbulent flows
Abstract
A semiempirical equation for a singlepoint velocity probability distribution in turbulent flow is proposed and analyzed. A general solution to the equation is presented, and its properties are analyzed for the case of homogeneous turbulence. A boundaryvalue problem is formulated and a numerical solution is obtained for steady flow in a flat duct (including the case where the friction forces at the walls are different. Results obtained are compared with available experimental data including third and forthorder moments.
