In the Fluid project, WorkPackage 1 is devoted to the creation of an image sequence
database with controlled 2D/3D experimental and numerical
ow elds. The objective of
this workpackage is to produce complete sets of data comprising:
meteorological satellite atmospheric image sequences;
rst sets of image sequences of controlled
uid mechanics experiments (air
ows in
wind tunnels), produced in a classical way using laser-sheets and cameras, with a
smoke or particle concentration chosen a priori in order to give reasonably detectable
contrasts;
second sets of experimental image sequences produced in an adapted manner (seeding,
lighting, frame size, physical data range) after feedback from tests conducted
in WP 2, WP 3 and WP 4;
synthetic image sequences coming from the results of Direct Numerical Simulations
(DNS) of shear
ows;
quantitative data characterising the
ows corresponding to each set of experimental
image sequences, among which global and local physical characteristics like velocity
elds, statistics, spatial correlation as well as topological dimensions of specic
regions of the
ow (formation length, layer thickness, virtual origins, wave length,
etc).
This report is the deliverable D1.23 on the production and diusion of
uid mechanics
images and data. All the dataset distributed during the rst year to the dierent partners
are described. Section 2 concerns two experimental datasets, the rst one is not time
resolved but the second is. Section 3 presents 2D-synthetic data of analytic
ows, DNS
of 2D sustained turbulent
ow and a sample of 2D
ow from PIV Challenge. The last
section 4 is devoted to 3D-synthetic data.
