Turbulence in fluid flows is characterized by a wide range of interacting scales. Since the
scale range increases as some power of the flow Reynolds number, a faithful simulation of …

Building upon the intrinsic properties of Navier-Stokes dynamics, namely the prevalence of
intense vortical structures and the interrelationship between vorticity and strain rate, we …

Intense fluctuations of energy dissipation rate in turbulent flows result from the self-
amplification of strain rate via a quadratic nonlinearity, with contributions from vorticity (via …

An efficient approach for extracting three-dimensional local averages in spherical
subdomains is proposed and applied to study the intermittency of small-scale velocity and …

The objective of this work is to investigate the interaction of turbulence with the nonlinear
processes of particle nucleation and growth that occur in reaction crystallisation, also known …

We solve the advection-diffusion equation for a stochastically stationary passive scalar θ, in
conjunction with forced 3D Navier-Stokes equations, using direct numerical simulations in …

We investigate the role of pressure, via its Hessian tensor ${\boldsymbol {H}} $, on
amplification of vorticity and strain-rate and contrast it with other inviscid nonlinear …

The reconstruction of incomplete information in flow fields is a pervasive challenge in
numerous turbulence-related applications. This paper proposes a framework for the high …

In this study, we revisit the spectral transfer model for the turbulent intensity in passive scalar
transport (under large-scale anisotropic forcing), and a subsequent modification to the …

The objective of the present paper is to investigate the effect of turbulent fluctuations on
precipitation and the implications for modelling. To this end, a coupled direct numerical …
