Subgrid-Scale Stress Modelling Based on the Square of the Velocity Gradient Tensor
A new subgrid scale model is proposed for Large Eddy Simulations in complex geometries. This model which is based on the square of the velocity gradient tensor accounts for the effects of both the strain and t...

High-Order Skew-Symmetric Jameson Schemes for Unsteady Compressible Flows
Performing reliable unsteady calculations on industrial configurations requires us to cope with both physical and numerical problems. As far as numerical problems are concerned, stable, low-cost, but accurate ...

Fluoxetine improves insulin sensitivity in obese patients with non-insulin-dependent diabetes mellitus independently of weight loss
OBJECTIVE: To study the effect of fluoxetine, a specific serotonin reuptake inhibitor, on insulin sensitivity in obese patients with non-insulin-dependent diabetes mellitus (NIDDM) independently of its action ...

Fluid Instabilities in Inertial Confinement Fusion
The design of optimized targets in the Inertial Confinement Fusion context requires instabilities to be estimated and mitigated whenever possible. Indeed, these processes might lead to shell break-up, therefor...

Large-Eddy Simulation of a Spatially-Develo** Boundary Layer
Two alternatives occurs for simulating transitional and fully-turbulent flows: first the simulation of all the scales involved in the motion (DNS), requiring tremendous resolution and CPU time, and second the ...

Subgrid-Scale Models based upon the Second-Order Structure-Function of Velocity
Large-eddy simulations of wakes and boundary layers are performed with the aid of the structure-function model [[1]] and two of its sequels, namely the filtered and selective structure- function models. It is fir...

Vortex Generation and Evolution in Numerical Simulation of Transitional Shear Flows
Vortex generation is investigated by means of three-dimensional numerical simulations with intensive use of visualizations. The following cases are considered:
direct simul...
