Calculation of the turbulent velocity profiles of a fully developed pipe flow
Abstract
Information regarding the functional relation between the turbulent exchange function and the flow and geometry quantities is needed for the computational determination of the turbulent velocity profiles in a pipe. An approach considered by Deissler (1959) provides a direct connection between flow and geometry quantities, and eliminates disadvantages of earlier gradient-dependent approaches. Experimental data are employed for an evaluation of the computed quantities. The present investigation is concerned with a development of the required turbulent exchange function regarding the momentum, taking into account the dependence of the values on the direct flow and geometry quantities. The results obtained in a determination of the velocity profiles on the basis of the considered approach are compared with results obtained by means of a gradient-dependent procedure.
