Biography
After completing my undergraduate education in Grenoble,
I graduated as an engineer from the Ecole Supérieure d Hydraulique
in Grenoble. I then prepared a Ph D at the Institut
de Mécanique de Grenoble under E.J. Hopfinger's supervision.
The subject dealt with statistical properties of small scale turbulence
and deviations from the theoretical predictions of Kolmogorov (1941). The
experiments I conducted were rather successful since reliable estimates
were obtained for velocity structure functions up to order 12. In 1984,
I was a post-doc fellow at the University
of Newcastle with R.A.
Antonia where I addressed other aspects of small scale turbulence,
e.g. the departure from isotropy of various turbulent flows. In 1986, I
started working as a CNRS Chargé de Recherche at the Institut
de Mécanique Statistique de la Turbulence (IMST - now IRPHE) in
Marseille. In 1995, I visited Japan and investigated on possibilities to
develop collaborations between IRPHE and Japanase Universities or Industrial
Research Insitutes (the
detailed report in French is available here).
In the last 15 years, I have conducted at
IRPHE (formerly IMST) experimental investigations of various turbulent
flows :
-
Turbulent
boundary layers with various wall conditions (riblets, suction, ...)
have been widely studied with L. Fulachier (with a strong collaboration
from J. Cousteix's group at ONERA-CERT
and from R.A. Antonia's at the University of Newcastle). We were
mainly interested in studying the detailed structure of such natural and
manipulated flows, in terms of basic turbulence properties as well as through
the contibutions of organized coherent structures such as ejections or
sweeps to the turbulent transport of momentum.
-
Experimental
and numerical investigations of variable density turbulent jets (mixing
of air, helium or CO2 with the ambient air) have been developed with M.
Amielh and L. Fulachier, in collaboration with M. Abid and R. Schiestel
(IRPHE) and J. Dusek (Univ. of Strasbourg). These flows are of fundamental
interest but they are also associated with various applications. The influence
of density variations is examined in great detail from two-component laser
Doppler velocimetry and PIV measurements. The near-field region and the
interface region are more specifically investigated. Note that the instabilities
appearing in an axisymmetric air jet at very low Reynolds numbers were
also studied through DNS by I.
Danaila. Instabilities appearing in variable density plane jets have
been studied, more recently, by S. Ravier.
-
Finally, my
recent contribution to the understanding of small scale properties
has concerned, on the one hand, the experimental investigation of joint
statistics between temperature and its dissipation and, on the other hand,
the development and the detailed analysis of the evolution equation for
the probability density function of temperature increments (with L.
Danaila and P.
Le Gal from IRPHE, J.F. Pinton
from ENS Lyon, A.
Pumir from INL Nice, J. Dusek from the Univ. of Strasbourg and S. Vaienti
from the Univ. of Toulon). A similar procedure was also applied with R.A.
Antonia (Univ. of Newcastle) to study pressure statistics and the second-
and fourth-order moments of velocity increments.
