Calculation of the hydrodynamic characteristics of the longitudinal flow of liquid around regular arrays of fuel element rods
P. A. Ushakov Institute for Physics and Power Engineering, Obninsk, Kaluga region
Abstract:
An approximate, analytic solution is given for the problem of the turbulent flow of a liquid around regular arrays of rods, obtained on the basis of an experimentally sound hypothesis concerning the universality of velocity profiles in ducts with a cross section contour of small curvature and a number of assumptions. Empirical coefficients are found from experiments with closely packed rods. A procedure proposed by Rothfus for annular ducts is utilized for large array spacings. A relatively simple procedure is proposed for the calculation of the hydrodynamic characteristics of longitudinally streamlined bundles.
