Spatio-temporal stability of the Kármán vortex street and the effect of confinement

François Gallaire, Cristobal Manuel Arratia Martinez, Saviz Mowlavi

The instability of the Kármán vortex street is revisited under a spatio-temporal perspective that allows the taking into account of the advection of the vortices by the external flow. We analyse a simplified point vortex model and show through numerical si ...

Critical inclination for absolute/convective instability transition in inverted falling films

Nicolas Igor Jacques Kofman

Liquid films flowing down the underside of inclined plates are subject to the interaction between the hydrodynamic and the Rayleigh-Taylor (R-T) instabilities causing a patterned and wavy topology at the free surface. The R-T instability results from the d ...

Soil–plant–atmosphere conditions regulating convective cloud formation above southeastern US pine plantations

Gabriele Manoli, Gabriel George Katul

Loblolly pine trees (Pinus taeda L.) occupy more than 20% of the forested area in the southern United States, represent more than 50% of the standing pine volume in this region, and remove from the atmosphere about 500 g C murn:x-wiley:13541013:media:gcb13 ...

Wake flow in a wind farm during a diurnal cycle

Fernando Porté Agel, Mahdi Abkar, Ahmad Sharifi

The atmospheric boundary layer (ABL) undergoes substantial changes in its structure and dynamics in the course of a day due to the transient nature of forcing factors such as the surface fluxes of heat and momentum. The non-stationary nature of the mean wi ...

Instability of two-phase co-axial jets at small Reynolds number

Laura Augello

A precise knowledge of co-axial flow dynamics and a better understanding of the mechanisms that act to destabilize the interface between the two fluids is of fundamental interest in many industrial applications like lubricated transport, injection devices, ...

On the Impact of Wind Farms on a Convective Atmospheric Boundary Layer

Fernando Porté Agel, Hao Lu

With the rapid growth in the number of wind turbines installed worldwide, a demand exists for a clear understanding of how wind farms modify land-atmosphere exchanges. Here, we conduct three-dimensional large-eddy simulations to investigate the impact of w ...

Absolute and convective instabilities of heated coaxial jet flow

Gioele Mariano Nicolò Balestra, Leonhard Kleiser

This study investigates the inviscid, linear spatio-temporal stability of heated, compressible, and incompressible coaxial jet flows. The influence of the temperature ratio and the velocity ratio between the core jet and the bypass stream on the transition ...

Development of a new 1D urban canopy model: coherences between surface parameterizations

Dasaraden Mauree, Alain Clappier

A 1-D Canopy Interface Model (CIM) was developed in order to better simulate the effect of urban obstacles on the atmosphere in the boundary layer. The model solves the Navier-Stokes equations on a high-resolved gridded vertical column. The effect of the s ...
