A model for the twopoint velocity correlation function in turbulent channel flow
Abstract
A relatively simple analytical expression is presented to approximate the equaltime, twopoint, doublevelocity correlation function in turbulent channel flow. To assess the accuracy of the model, we perform the spectral decomposition of the integral operator having the model correlation function as its kernel. Comparisons of the empirical eigenvalues and eigenfunctions with those constructed from direct numerical simulations data show good agreement. {copyright} {ital 1996 American Institute of Physics.}
