Abstract

This paper deals with the behaviour of suspended solid particles in isotropous, homogeneous and gradually decaying turbulent flows. Kraichnan's spectral description of the turbulent field is employed to investigate the influence of the particle size and mass on the Lagrangian parameters. The procedure is validated by making use of existing data on turbulent solid transport and it is shown to be a reliable as well as a reasonably cheap tool to evaluate the behaviour of suspended solid particles. 1 Introduction The interaction between suspended particles and turbulent flow is of great importance in many practical problems. Some aspects of the basic case of low particle concentration in isotropous, homogeneous or gradually decaying turbulent flow, however elementary these flow condit
