The efficiency of turbulent mixing in stratified fluids
Mixing is a common feature of stratified fluids. In stratified fluids the density varies with the height. This is true for the most fluids in geophysical environments, like lakes, the atmosphere or the ocean. Turbulent mixing plays a crucial role for the overall energy budget of the earth and has …

Turbulent mixing of unpremixed reactants in stirred tanks.
The turbulent mixing process between two liquid streams in a standard tank stirred by a Rushton turbine has been studied. Experimental measurements of concentration and segregation (fluctuating concentration) have been made for both reacting and non-reacting flows. For the non-reacting case, one …

Growth Suppression in Simulated Compressible Turbulent Mixing Layers
Direct numerical simulations of turbulent flows require numerical schemes with high resolution and grid flexibility. Resolution properties of B-spline and compact finite-difference schemes are evaluated using Fourier analysis in periodic domains, and tests based on solution of the wave and heat …

An experimental investigation of compressible, turbulent mixing layers
An investigation of compressible, turbulent mixing layers has been completed. The experiments were conducted using pressure measurements, schlieren photography and velocity measurements with a two-component laser Doppler velocimeter system. These diagnostic systems were developed for use with the …

Dynamically induced uncertainty in stratified turbulent mixing models
… the ocean, it is necessary to model small-scale turbulent processes and the way in which they enhance mixing in order to form an accurate picture of the vertical transport of heat, nutrients and anthropogenic pollutants. This applies to parameterisation schemes in coarsely resolved large-scale …

Turbulent mixing in stratified fluids : layer formation and energetics
A turbulent mixing experiment was conducted to observe the dynamics and the energetics of layer formation along with the region of layer formation in the Reynolds number (Re) and the overall Richardson number (Rio) space. A salt stratified fluid was mixed uniformly throughout its depth with a …

Characterisation of turbulent mixing and its influence on antisolvent crystallisation
Mixing is a fundamental part of many processes in chemical engineering. In order for molecular processes to proceed there is an implicit requirement for molecular scale mixing. Many processes are so slow that they are effectively independent of mixing as mixing is fast relative to the process. …

On the Growth Rate of Turbulent Mixing Layers: A New Parametric Model
<p>A new parametric model for the growth rate of turbulent mixing layers is proposed. A database of experimental and numerical mixing layer studies was extracted from the literature to support this effort. The domain of the model was limited to planar, spatial, nonreacting, free shear layers that …

Fluctuating Velocity-Pressure Field Structure in a Round Jet Turbulent Mixing Region
An experimental study of turbulent mixing has been conducted to provide detailed insight regarding the turbulent transport processes, especially those involving pressure. The investigation was conducted in the mixing region of a 6.35 cm diameter, isothermal, stationary jet having an exit velocity …
