AbstractThe problem of longitudinal dispersion of heavy particles of finite size in a horizontal circular pipe carrying a steady turbulent flow was incompletely dealt with in the classical work of Elder [J. Fluid Mech. 5 (1959) 544]. In this paper, the problem is re-examined and a formal expression in terms of a cell function for the dispersion coefficient is deduced using an asymptotic analysis. The dispersion coefficient can be calculated upon finding numerically the first few components of the Fourier expansion of the cell function. Prediction by the present theory is found to agree better than Elder's theory with some published experimental data. © 2001 Elsevier Science Ltd. All rights reserved.
