▪ 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 …

Scalar dissipation is of great importance in the theory and modelling of combustion and
other reacting turbulent flows. Measurements of scalar dissipation are found to lack the …

A simultaneous planar Rayleigh scattering and planar laser-induced fluorescence (PLIF)
technique is described which allows planar measurement of the full three-dimensional …

Statistics of the mixed velocity–passive scalar field and its Reynolds number dependence
are studied in quasi-isotropic decaying grid turbulence with an imposed mean temperature …

Direct numerical simulations of temporally developing, three-dimensional, CH 4/CO 2, CH
4/O 2, and CO 2/O 2 mixing layers are conducted at a supercritical pressure of 300 atm. To …

Simultaneous measurements of two velocity components and temperature are performed
combining Laser Doppler Anemometry (LDA) and cold wire thermometry. LDA is a common …

The influence of probe resolution on the statistical measurement of a passive scalar is
reported. A spectral method is employed to simulate degradation of the spatial resolution of …

The passive scalar field of a temporally evolving shear layer is investigated using gradient
trajectories as a means to analyse the scalar probability density function and the conditional …

This study is an experimental investigation of the probability density function (pdf) and the
fine structure of temperature fluctuations in uniformly sheared turbulence with a passively …

The statistical behavior of the fluid and particle temperatures in homogeneous two-phase
turbulent flows are investigated via direct numerical simulations. The effects of the flow …
