Decaying turbulence in neutral and stratified fluids

چکیده
which is considerably longer than previous measurements at the same mesh Reynolds number (Re = 48260). The stratified experiment resulted in a decay rate virtually identical to that of the neutral case through W,t/M = 275. However the decay rate sharply decreased after this time when the field of turbulence was replaced by internal gravity waves. A critical Richardson number marks the transition from the turbulence to an internal gravity wave domain.

Energy development of decaying isotropic turbulence in a 3-D periodic cube with non-rotating or rotating frames of reference is studied through direct numerical simulation using GPU accelerated lattice Boltzmann method. The initial turbulence is isotropic, generated in spectral space with prescribed energy spectrum E(κ)~κm in a range between κmin and ...
متن کاملBiogenic mixing induced by intermediate Reynolds number swimming in stratified fluids
We study fully resolved motion of interacting swimmers in density stratified fluids using an archetypal swimming model called "squirmer". The intermediate Reynolds number regime is particularly important, because the vast majority of organisms in the aphotic ocean (i.e. regions that are 200 m beneath the sea surface) are small (mm-cm) and their motion is governed by the balance of inertial and ...
متن کاملNumerical Predictions of Turbulent Mixed Convection Heat Transfer to Supercritical Fluids Using Various Low Reynolds Number k-e Turbulence Models
There are a number of systems in which supercritical cryogenic fluids are used as coolants or propellant fluids. In some modern military aircraft, the fuel is pressurized above its critical point and used as a coolant to remove heat from the aircraft engine. Accurate prediction of heat transfer coefficients to turbulent flows of supercritical fluids is essential in design of such systems. One o...
متن کاملNumerical Modeling of Saline Gravity Currents Using EARSM and Buoyant k- Turbulence Closures
Gravity currents are very common in nature and may appear in rivers, lakes, oceans, and the atmosphere. They are produced by the buoyant forces interacting between fluids of different densities and may introduce sediments and pollutants into water bodies. In this study, the hydrodynamics and propagation of gravity currents are investigated using WISE (Width Integrated Stratified Environments), ...
متن کاملEnergetics aspects in Direct Numerical Simulations of a turbulent stratified flow: irreversible mixing
Direct Numerical Simulations of a linearly stratified bounded fluid in decaying turbulence are performed. The abscence of vertical periodicity allows the stratification of the system to evolve in time. We observe that mixing efficiency increases as a function of the Richardson number Ri, and saturates to a maximum value of 0.25. This evolution adjusts quantitatively to the statistical predictio...
