Ask for a financing application.

General informations

In this page you can apply for a financing  application  for either a mission or a conference.

Deadlines

Depending on whether the application is for a mission or a conference, it should be submitted between 2 and 3 months in advance, see the links below.

Deliberation

The funding applications will be examinated at the beginning of each month by the Steering Committee (SC). The SC will evaluate the quality and scientific content of the application, together with its relevance for the french-italian collaborations that the LYSM wants to favour, and the reasonableness of the financial plan. The decision will be taken after a vote of the SC.

Results

The decisions of the SC are communicated to the applicants as soon as possible, usually in the second half of the month when the demand is examined. The successful applicant is requested either to insert the LYSM logo on the website and poster of the supported conference, or to acknowledge the "financial support of the LIA LYSM AMU CNRS ECM INdAM" in the scientific publications connected with the funded mission.

On the efficiency of laminar and turbulent mixing in wall-bounded flows. B. Kadoch, W.J.T. Bos & K. Schneider.

2019/10/25

 

A turbulent flow mixes in general more rapidly a passive scalar than a laminar flow does. From an energetic point of view, for statistically homogeneous or periodic flows, the laminar regime is more efficient. However, the presence of walls may change this picture. We consider in this investigation mixing in two-dimensional laminar and turbulent wall-bounded flows using direct numerical simulation. We show that for sufficiently large Schmidt number, turbulent flows more efficiently mix a wall-bounded scalar field than a chaotic or laminar flow does. The mixing efficiency is shown to be a function of the Péclet number, and a phenomenological explanation yields a scaling law, consistent with the observations.
