Abstract A unified theory of frontogenesis in mixed layers is proposed. Analytical solutions of the nonlinear mass and density balances in a mixed layer are found in the Lagrangian frame for a wide class of entrainment parameterizations. These solutions show mixed-layer depth and density to be functions of particle position and separation, where mixing

Buoyancy is the dominant mechanism driving turbulence in a convective boundary layer. Such turbulence is not completely random, but is often organized into identifiable structures such as thermals and plumes (Young, 1988). Entertainment happens at a variety of scales: lateral entertainment by small eddies into the sides of thermals, and vertical ...

Laser-induced fluorescence (LIF) diagnostics and highspeed, real-time digital image acquisition techniques are combined to map the composition field in a water mixing layer. A fluorescent dye, which is premixed with the lowspeed freestream fluid and dilutes by mixing with the highspeed fluid, is used to monitor the relative concentration of high-speed ...

Molecular mixing layers in stellar outflows
Astrophysics and Space Science, 1995High velocity jets from young stars interact with the surrounding molecular environment and molecular outflows quite possibly are the result. This interaction can take place through the formation of a turbulent mixing layer. Models have been constructed (following Cant/’o and Raga) of a plane mixing layer in the boundary between a high velocity, atomic

Mixed-Layer Models with Second-Layer Dependence
The Journal of Geology, 1967A succession of packets (multiple layers) characterized in terms of a two-packet Markov-2 model can be redefined in terms of a four-packet Markov-1 model by specifying the relative abundance of the two kinds of packets together with the transition probabilities $p_{11.1}, p_{21.1}, and p_{22.1}$.

Mixed Layer Moisture structure
Monthly Weather Review, 1976Abstract Radiosonde data from the National Hail Research Experiment and the Wangara experiment are examined to study vertical gradients of moisture in heated boundary layers which are well-mixed in virtual potential temperature. The frequent occurrence of a significant decrease of moisture with height in the mixed layer over the high plains region of ...

A mixing layer develops between two parallel, but different velocity, streams separated by a splitter plate upstream. The mixing layer is a flow of paramount importance for understanding the development of turbulence in external aerodynamics or combustion, as well as in atmospheric or oceanic flows. These so-called “spatially-growing mixing layers” are

Numerical simulation of compressible mixing layers
International Journal of Heat and Fluid Flow, 2005Abstract Three-dimensional spatially developing compressible planar mixing layers are studied numerically for convective Mach number M c = 0.4, 0.8 and 1.2. The present results for the flow-field structures, the mean velocity profiles, the mixing-layer growth rate and Reynolds stresses agree well with those of experiments and other numerical ...

Comparison of confined, compressible, spatially developing mixing layers with temporal mixing layers
AIAA Journal, 1993The spatially developing mixing layer is investigated using both linear stability theory and numerical simulations. Temporal and spatial linear stability solutions are compared, and it is found that the temporal and spatial wave numbers are equal, the temporal frequency is a function of the spatial frequency, and the temporal and spatial growth rates ...

AIP Conference Proceedings, 2005
Turbulent mixing layers have been proposed to explain observations of line ratios of highly ionized elements in the interstellar medium. We present preliminary results of numerical simulations of turbulent mixing layers in a magnetized medium. We developed a MHD code with radiative cooling.
