Temperature front formation in stably stratified turbulence

چکیده
Temperature fronts and associated cliff-ramp structures in stably stratified turbulence are investigated using DNS of the Navier-Stokes equations under the Bousinesq approximation. Vertical profiles of temperature fluctuations show sawtooth wave structures which result in a skewed PDF of the derivative of temperature fluctuation in the z-direction. The mechanisms for generating and maintaining these structures are considered.

Temperature statistics in two-dimensional stably stratified turbulence.
Using two-dimensional direct numerical simulations, the statistics of temperature differences in stably stratified turbulence are studied. Comparison with passive scalar statistics in similar flows suggests that the stably stratified case is qualitatively similar to the passive case. Probability distribution functions of temperature differences between points separated by different distances co...
متن کاملTangling clustering of inertial particles in stably stratified turbulence.
We have predicted theoretically and detected in laboratory experiments a tangling clustering of inertial particles in a stably stratified turbulence with imposed mean vertical temperature gradient. In the stratified turbulence a spatial distribution of the mean particle number density is nonuniform due to the phenomenon of turbulent thermal diffusion, i.e., the inertial particles are accumulate...
متن کاملAnalytical and Numerical Studies of Natural Convection along Doubly Infinite Vertical Plates in Stratified Fluids
Results are presented from a series of analytical and numerical studies of buoyantly driven flows along heated vertical surfaces immersed in stably stratified fluids. Flows of the studied type are broadly represented in engineering and geophysical applications. First, the classical problem of one-dimensional natural convection flow along a heated wall is revisited for the case of a stably strat...
متن کاملPreferential concentration of heavy particles in stably stratified turbulence.
The effect of preferential concentration of heavy particles in a homogeneous stably stratified turbulent flow is studied by means of direct numerical simulations. Particle distributions show different clustering patterns in horizontal and vertical directions, thereby representing the anisotropy of the flow. Preferential concentration in stably stratified turbulence can be quantified using 2D an...
متن کاملOn the Arctic Boundary Layer On the Arctic Boundary Layer
The boundary layer is the part of the atmosphere that is in direct contact with the ground via turbulent motion. At mid-latitudes the boundary layer is usually one or a few kilometers deep, while in the Arctic it is much more shallow, typically a few hundred meters or less. The reason is that here the absolute temperature increases in the lowest kilometer, making the boundary layer semi-permane...
