Navier-Stokes–based linear model for unstably stratified turbulent channel flows
نویسندگان
چکیده
We use a simple linearized Navier-Stokes-based model to study the large-scale quasistreamwise rolls in unstably stratified turbulent channel flows. As influence of buoyancy-driven mechanisms (relative shear-driven mechanisms) increases, channel-wide structures with two-peaks intensity temperature emerges from linear model, consistent direct numerical simulations.

Linear dynamics of the solar convection zone: excitation of waves in unstably stratified shear flows
In this paper we report on the nonresonant conversion of convectively unstable linear gravity modes into acoustic oscillation modes in shear flows. The convectively unstable linear gravity modes can excite acoustic modes with similar wave-numbers. The frequencies of the excited oscillations may be qualitatively higher than the temporal variation scales of the source flow, while the frequency sp...
متن کاملA Non-Fickian Mixing Model for Stratified Turbulent Flows
The long term goal of this project is to develop a better understanding of oceanic processes in the range of 100 m to 10 km, in the so-called submesoscale range. In particular, it is important to explore and find out whether and what type of submesoscale instabilities exist, how they are connected to both larger scale and smaller scale motions, and to what extent they influence transport proces...
متن کاملTurbulent mixing of stratified flows
A mathematical model for turbulent mixing of stratified, sheared flows is developed and explored. Two applications are emphasized, one to the dynamics of the ocean well–mixed layer, and another to the analysis of the stability of equilibrium profiles away from boundaries.
متن کاملStochastic Navier-Stokes Equations for Turbulent Flows
This paper concerns the fluid dynamics modelled by the stochastic flow η̇ (t, x) = u (t,η (t, x)) + σ (t,η (t, x)) ◦ Ẇ η(0, x) = x where the turbulent term is driven by the white noise Ẇ . The motivation for this setting is to understand the motion of fluid parcels in turbulent and randomly forced fluid flows. Stochastic Euler equations for the undetermined components u(t, x) and σ(t, x) o...
متن کاملTurbulent mixing in strongly stratified shear flows
Motivated by the importance of irreversible mixing in geophysical and environmental flows, we seek to understand the dependence of its efficiency under strongly stratified conditions through a seris of direct numerical simulation of Holmboe wave instability under various initial conditions. Our numerical findings demonstrate that while mixing is enhanced when the density layer is much sharper t...
