Particle-Pair Relative Velocity Measurement in High-Reynolds-Number Homogeneous and Isotropic Turbulence Using 4-Frame Particle Tracking Velocimetry
Zhongwang Dou, Peter J. Ireland, Andrew D. Bragg +3
The radial relative velocity between particles suspended in turbulent flow plays a critical role in droplet collision and growth. We present a simple and accurate approach to RV me…
Effects of Reynolds Number and Stokes Number on Particle-pair Relative Velocity in Isotropic Turbulence: A Systematic Experimental Study
Zhongwang Dou, Andrew D. Bragg, Adam L. Hammond +3
The effects of Reynolds number and Stokes number on particle-pair relative velocity (RV) were investigated systematically using a recently developed planar four-frame particle trac…
The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part I: Simulations without gravitational effects
Peter J. Ireland, Andrew D. Bragg, Lance R. Collins
In this study, we analyze the statistics of both individual inertial particles and inertial particle pairs in direct numerical simulations of homogeneous isotropic turbulence in th…
The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part II: Simulations with gravitational effects
Peter J. Ireland, Andrew D. Bragg, Lance R. Collins
In Part I of this study, we analyzed the motion of inertial particles in isotropic turbulence in the absence of gravity using direct numerical simulation (DNS). Here, in Part II, w…
On the relationship between the non-local clustering mechanism and preferential concentration
Andrew D. Bragg, Peter J. Ireland, Lance R. Collins
`Preferential concentration' (\emph{Phys. Fluids} \textbf{A3}:1169--78, 1991) refers to the clustering of inertial particles in the high-strain, low-rotation regions of turbulence.…
Mechanisms for the clustering of inertial particles in the inertial range of isotropic turbulence
Andrew D. Bragg, Peter J. Ireland, Lance R. Collins
In this paper, we consider the physical mechanism for the clustering of inertial particles in the inertial range of isotropic turbulence. We analyze the exact, but unclosed, equati…
Forward and backward in time dispersion of fluid and inertial particles in isotropic turbulence
Andrew D. Bragg, Peter J. Ireland, Lance R. Collins
In this paper we investigate both theoretically and numerically the forward in time (FIT) and backward in time (BIT) dispersion of fluid and inertial particle pairs in isotropic tu…
