A large-eddy simulation (LES) of a next-generation combustor is performed to examine
effects of this combustor concepts on direct and indirect combustion noise characteristics …

The $ n $ th-order velocity structure function $ S_n $ in homogeneous isotropic turbulence is
usually represented by $ S_n\sim r^{\zeta _n} $, where the spatial separation $ r $ lies within …

This study focuses on the evaporation and mixing process in turbulent two-phase flows with
a direct resolution of the flow near the interface. A first approach, using a passive scalar to …

The variation of has obvious ramifications for small-scale turbulence research since it
violates the modified similarity hypothesis introduced by Kolmogorov (J. Fluid Mech., vol. 13 …

The scaling behavior of the moments of two passive scalars that are excited by two different
methods and simultaneously convected by the same isotropic steady turbulence at R λ= 805 …

We study the relaxation of an initially segregated scalar mixture in a randomly stirred
medium, aiming at describing the overall concentration distribution of the mixture, its shape …

The exchange of scalars between the biosphere and the atmosphere has direct bearing on
a large number of problems such as climate change, air and water quality, agricultural …

This paper describes a novel hybrid method, combining a spectral and a particle method, to
simulate the turbulent transport of a passive scalar. The method is studied from the point of …

Turbulent mixing of passive scalars is studied in the canonical shock–turbulence interaction
configuration via shock-capturing direct numerical simulations, varying the shock Mach …

Connections between the wall-normal turbulent velocity spectrum E ww (k) at wave number
k and the mean velocity profile (MVP) are explored in pressure-driven flows confined within …
