Turbulence Modeling in Stratified Flows over Topography
نویسنده
چکیده
A non-hydrostatic code that numerically solves the unsteady, three-dimensional, primitive equations is used. Advanced models such as the dynamic mixed model and the dynamic eddy viscosity model are utilized to represent subgrid processes in the LES approach. A novel near-wall model has been developed so as to increase the Reynolds number of boundary flows to realistically large geophysical values. The code is capable of capturing the effect of bottom slopes, small-scale roughness, and oscillatory forcing.

2DV Nonlinear k-ε Turbulence Modeling of Stratified Flows
The commonly used linear k-ε turbulence model is shown to be incapable of accurate prediction of turbulent flows, where non-isotropy is dominant. Two examples of non-isotropic flows, which have a wide range of applications in marine waters, are saline water flow and the stratified flows due to temperature gradients. These relate to stratification and consequently, variation of density through...
متن کاملThe Effect of Curvature on Turbulence in Stratified Fluids
The influence of streamline curvature on small-scale turbulence and vertical mixing in stratified fluids is the subject of this study. The roles of curvature and stratification in enhancing and suppressing turbulent mixing are explored using second-moment closure for turbulence. Governing equations for second moments are expressed in generalized orthogonal curvilinear coordinates, from which, t...

Flows of natural hydro-environments are usually turbulent and mostly stratified, like the flows in lakes, reservoirs, estuaries and atmosphere to name a few. In stratified flows due to the buoyancy forces, the turbulent stresses are usually non-isotropic. Therefore the accuracy of the numerical simulations for such flows is highly dependent on the turbulence model and the implementation of non-...

[1] Quantifying diapycnal mixing in stably stratified turbulence is fundamental to the understanding and modeling of geophysical flows. Data of diapycnal mixing from direct numerical simulations of homogeneous stratified turbulence and from grid turbulence experiments, are analyzed to investigate the scaling of the diapycnal diffusivity. In these homogeneous flows the instantaneous diapycnal di...
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...
