Turbulent-laminar patterns in plane Poiseuille flow

Turbulent-laminar banded patterns in plane Poiseuille flow are studied via direct numerical simulations in a tilted and translating computational domain using a parallel version of the pseudospectral code Channelflow. 3D visualizations via the streamwise v ...

Wind-tunnel experiments of thermally-stratified turbulent boundary layer flow over a wall-mounted 2-D block

Fernando Porté Agel, Wei Zhang, Corey Dean Markfort

Turbulent boundary-layer flows over complex topography have been extensively studied in the atmospheric sciences and wind engineering communities. The upwind turbulence level, the atmospheric thermal stability and the shape of the topography as well as sur ...

Advancing plasma turbulence understanding through a rigorous Verification and Validation procedure: a practical example

Paolo Ricci

The methodology used to assess the reliability of numerical simulation codes constitutes the Veri- fication and Validation (V&V) procedure. V&V is composed by two separated tasks: the verifica- tion process, which is a mathematical issue targeted to assess ...

On the energy dissipation rate of solutions to the compressible isentropic Euler system

Elisabetta Chiodaroli

In this paper we extend and complement the results in [4] on the well-posedness issue for weak solutions of the compressible isentropic Euler system in 2 space dimensions with pressure law

p(\rho) = \rho^\gamme, \geq 1

. First we show that every Riemann p ...

Investigation of droplet shedding in flow focusing geometries using the boundary element method.

François Gallaire, Mathias Nagel

Shedding of droplets in a flow focusing junction is standard technique in two-phase microfluidics. This break-up is driven by a capillary instability. Here we present a depth-averaged approach to simulate these complex phenomena. Since the physical mechani ...

Large eddy simulation of the differentially heated cubic cavity flow by the spectral element method

Michel Deville, Emmanuel Leriche, Christoph Bosshard, Alfredo Soldati, Riccardo Puragliesi, Abdelouahab Dehbi

Large eddy simulations of the turbulent natural convection flow in a differentially heated cavity have been carried out at a Rayleigh number of 10(9) using the spectral element method. To obtain the large eddy simulation equations, a low pass filter given ...

A New Sensor Platform for Investigating Turbulence in Stratified Coastal Environments

Ulrich Lemmin, Damien Bouffard

Characterizing and quantifying vertical exchange processes is essential for understanding physical and biological dynamics in stratified lakes and oceans. Unfortunately, the role of mixing is still poorly understood because of the challenges of conducting ...
