Role of viscoelasticity in the appearance of low-Reynolds turbulence: considerations for modelling

Journal of Biological Engineering
Inertial effects caused by perturbations of dynamical equilibrium during the flow of soft matter constitute a hallmark of turbulence. Such perturbations are attributable to an imbalance between energy storage and energy dissipation.

Numerical Investigation of Scaling Properties of Turbulent Premixed Flames [PDF]

arXiv, 1997
Gibson scaling and related properties of flame-surface geometry in turbulent premixed combustion are demonstrated using a novel computational model, Deterministic Turbulent Mixing (DTM). In DTM, turbulent advection is represented by a sequence of maps applied to the computational domain.

Model of the Height Variation of the Turbulence Kinetic Energy Budget in the Unstable Planetary Boundary Layer

, 1974
A model is proposed for the variation with height of the terms in the turbulence kinetic energy budget throughout an unstably stratified barotrople planetary boundary layer. The model is based upon aircraft measurements throughout the boundary layer that

Effects of Turbulence Modeling on the Simulation of Wind Flow over Typical Complex Terrains

Applied Sciences
The correct prediction of the wind speed and turbulence levels over complex terrain is essential for accurately assessing wind turbine wake recovery, power production, safety, and wind farm design.

Buoyant production and consumption of turbulence kinetic energy in cloud-topped mixed layers

, 1984
Entrainment closure theories for mixed-layer models entail assumptions about how the net rate of buoyant production of turbulence kinetic energy is partitioned into gross production and consumption. Three alternative partitioning theories are examined in

Sub-Alfvénic Turbulence: Magnetic-to-kinetic Energy Ratio, Modification of Weak Cascade, and Implications for Magnetic Field Strength Measurements

The Astrophysical Journal
We study the properties of sub-Alfvénic magnetohydrodynamic (MHD) turbulence, i.e., turbulence with Alfvén mach number M _A = V _L / V _A < 1, where V _L is the velocity at the injection scale and V _A is the Alfvén velocity.
