Abstract Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM) instabilities are well-known
pathways towards turbulent mixing layers, in many cases characterized by significant mass …

▪ Abstract Passive scalar behavior is important in turbulent mixing, combustion, and pollution
and provides impetus for the study of turbulence itself. The conceptual framework of the …

The mixing of the round jet normal to a uniform crossflow is studied for a range of jet-to-
crossflow velocity ratios, r, from 5 to 25. Planar laser-induced fluorescence (PLIF) of acetone …

Data on turbulent mixing and other turbulent-flow phenomena suggest that a (mixing)
transition, originally documented to occur in shear layers, also occurs in jets, as well as in …

▪ Abstract The ability of turbulent flows to effectively mix entrained fluids to a molecular scale
is a vital part of the dynamics of such flows, with wide-ranging consequences in nature and …

Several simple mathematical models for the turbulent diffusion of a passive scalar field are
developed here with an emphasis on the symbiotic interaction between rigorous …

A critical review of both experimental and computational studies of round turbulent jets is
provided, beginning with the work of Tollmien (1926). This review traces the history, the …

The influence of initial flow conditions on the passive scalar field of a turbulent free jet
issuing from the round nozzle is investigated in this paper by a review of the literature and a …

Experiments were conducted in a two-stream planar mixing layer at convective Mach
numbers, Mc, of 0.28, 0.42, 0.50, 0.62 and 0.79. Planar laser Mie scattering (PLMS) from a …

The statistically stationary state of a turbulently advected passive scalar is studied, with an
imposed linear mean gradient in two dimensions, via a number of numerical experiments …
