Decay characteristics of turbulent kinetic energy and enstrophy in grid turbulence have been
investigated in the far downstream region (⁠ x/M∼ 10 3⁠: x is the downstream distance from …

The analytical framework based on the similarity hypotheses of Kolmogorov and Obukhov
arguably provides an adequate description of homogeneous isotropic turbulence at very …

We present an empirical but simple and practical spectral chart method for determining the
mean turbulent kinetic energy dissipation rate\left ⟨ ε\right ⟩ in a variety of turbulent flows …

When a liquid stream is injected into a gaseous atmosphere, it destabilizes and continuously
passes through different states characterized by different morphologies. Throughout this …

The general focus of this paper is on the mixing of a passive scalar for Sc= 1 (Sc is the
Schmidt number) in decaying homogeneous isotropic turbulence for which the initial …

The paper examines the validity of velocity and scalar invariants in slightly heated and
approximately isotropic turbulence generated by passive conventional grids. By assuming …

In slightly heated grid turbulence, the mean turbulent kinetic energy and passive-scalar
variance dissipation rates,<∊> and< χ>, decay according to power laws. The isotropic forms …

Scaling of grid turbulence with a constant mean cross-stream temperature gradient is
investigated using a combination of theoretical predictions and experimental data. A novel …

Corrsin equation closure is done using the gradient hypothesis relating a two-point third-
order correlation moment to a two-point second-order correlation function of a passive scalar …

A direct numerical simulation (DNS) based on the lattice Boltzmann method (LBM) is carried
out in low-Reynolds-number grid turbulence to analyse the mean turbulent kinetic energy …
