Analysis of scale-dependent kinetic and potential energy in sheared, stably stratified turbulence
Xiaolong Zhang, Rohit Dhariwal, Gavin Portwood +2
Budgets of turbulent kinetic energy (TKE) and turbulent potential energy (TPE) at different scales in sheared, stably stratified turbulence are analyzed using a filtering ap…
Hydrodynamic interactions and extreme particle clustering in turbulence
Andrew D. Bragg, Adam L. Hammond, Rohit Dhariwal +1
From new detailed experimental data, we found that the Radial Distribution Function (RDF) of inertial particles in turbulence grows explosively with scaling as the collisi…
Clustering of Rapidly Settling, Low-Inertia Particle Pairs in Isotropic Turbulence. II. Comparison of Theory and DNS
Sarma L. Rani, Rohit Dhariwal, Donald L. Koch
Part I of this study presented a stochastic theory for the clustering of monodisperse, rapidly settling, low-Stokes-number particle pairs in homogeneous isotropic turbulence. The t…
Enhanced and suppressed multiscale dispersion of bidisperse inertial particles due to gravity
Rohit Dhariwal, Andrew D. Bragg
Using Direct Numerical Simulations (DNS), we investigate how gravity modifies the multiscale dispersion of bidisperse inertial particles in isotropic turbulence. The DNS has a Tayl…
The influence of Reynolds and Froude number on the motion of settling, bidisperse inertial particles in turbulence
Mohammadreza Momenifar, Rohit Dhariwal, Andrew D. Bragg
Using Direct Numerical Simulations (DNS), we examine the effects of Taylor Reynolds number, , and Froude number, , on the motion of settling, bidisperse inertial particles…
Do fluid particles separate exponentially in the dissipation range?
Rohit Dhariwal, Andrew D. Bragg
In this paper we consider how the statistical moments of the separation between two fluid particles grow with time when their separation lies in the dissipation range of turbulence…
Small-scale dynamics of settling, bidisperse particles in turbulence
Rohit Dhariwal, Andrew D. Bragg
We use Direct Numerical Simulations (DNS) to investigate the dynamics of settling, bidisperse particles in isotropic turbulence. In agreement with previous studies, we find that wi…
