Abstract
Heavy particle clustering in turbulence is discussed from both phenomenological and analytical points of view, where the power law of the pair-correlation function is obtained in the inertial range. A closure theory explains the power law in terms of the balance between turbulence mixing and preferential-concentration mechanism. The obtained power law is supported by a direct numerical simulation of particle-laden turbulence.
