Study of Colliding Particle-Pair Velocity Correlation in Homogeneous Isotropic Turbulence
Applied Sciences, 2020 This paper deals with the numerical analysis of the particle inertia and volume fraction effects on colliding particle-pair velocity correlation immersed in an unsteady isotropic homogeneous turbulent flow.

Energies, 2020 Wind turbines are usually clustered in wind farms which causes the downstream turbines to operate in the turbulent wakes of upstream turbines. As turbulence is directly related to increased fatigue loads, knowledge of the turbulence in the wake and its ...

Turbulent Eddy Generation for the CFD Analysis of Hydrokinetic Turbines
Journal of Marine Science and Engineering, 2022 This paper presents a novel theoretical and computational methodology for the generation of an onset turbulent field with prescribed properties in the numerical simulation of an arbitrary viscous flow.

von Kármán-Howarth and Corrsin equations closures through Liouville theorem
Results in Physics, 2020 In this communication, the closure formulas of von Kármán-Howarth and Corrsin equations are obtained through the Liouville theorem and the hypothesis of homogeneous isotropic incompressible turbulence.

Triple Decomposition of Velocity Gradient Tensor in Compressible Turbulence
Fluids, 2021 The decomposition of the local motion of a fluid into straining, shearing, and rigid-body rotation is examined in this work for a compressible isotropic turbulence by means of direct numerical simulations.

Modulation of homogeneous and isotropic turbulence in emulsions [PDF]
Journal of Fluid Mechanics, 2021 We present a numerical study of emulsions in homogeneous and isotropic turbulence (HIT) at $Re_\lambda =137$. The problem is addressed via direct numerical simulations, where the volume of fluid is used to represent the complex features of the liquid ...

New Journal of Physics, 2018 In statistically stationary conditions, the turbulent energy spectrum in a high Reynolds number flow exhibits a k ^−5/3 (Kolmogorov) regime, with a faster decay at larger, dissipative wavenumbers.
