1 - Presentation (Nov.2008-Nov.2010) Formerly as LME, the DF2T team has built scientific expertise in the fields of heat and mass transfer in

fluids. Applied research activities foster deeper knowledge and understanding of physical

phenomena, closer to fundamental research.

DF2T is strongly involved in experimental research focused on the analysis of near wall fluid flow and

heat transfer phenomena, in connection with applications to transport systems. The research topics

are currently dealing with the unsteady wall shear stress, identification of turbulent coherent

structures and their control, pressure waves in tunnels, convective heat transfer in rotating systems

and impinging jets, thermal dissipations in friction brakes and the thermal and hydrodynamic

behaviour of multiphase flows.

Heat Transfer Enhancement and Control Research carried out by the group members mainly deals with heat transfer by convection. The aim is

to understand the fundamentals of the phenomena to control them in order to increase the

performance of the systems in which they are included. When not possible to control the phenomena,

the studies focus on the prediction of their evolution and of their consequences. Presently, two

research fields are covered: interfaces and propagating phenomena in confined geometries.

Concerning the interfaces, they are of three types: fluid/solid, solid/solid, and liquid/gas. On one hand,

they are studied experimentally. On the other hand, they are modeled and numerically studied. To

cover a broad spectrum of boundary conditions, various test benches are available. This makes

possible the understanding of the fundamental phenomena governing the heat transfer. To do so, it is

necessary to develop new non specialized analysis techniques. For this kind of experiments, it is

mandatory not to disturb or modify the flow pattern and/or the temperature field. Hence, new

measuring techniques have been developed by the group members. As mentioned, these techniques

are coupled with modeling and numerical simulations; the scale starting at the local level for

instabilities, and ending at the global level for "system representations".

( Railway motors cooling) channels of rectangular cross-section

Modeling wave-like propagation phenomena in confined fluid areas is particularly challenging, as

transmission, reflection and superposition processes build intricate wave patterns. Research in this

field focuses on the development of dedicated models and solution algorithms with substantially

higher efficiency than the prevailing all-purpose flow solvers. Originally developed for the simulation

of high speed trains circulating in tunnels, a set of models with growing complexity has been

conceived, covering the various scenarios of interest. Additional relevant features have been

implemented, modeling a wide range of potential applications: migration of solid particles in a fluid

medium and blast waves travelling in confined networks.

The applications of the research work are found in numerous technical fields: electrical motors or

generators, brakes, heat pipes, heat exchangers, tunnels, underground galleries.

Near wall turbulence and control

The main goal of this research topic is to contribute to a better understanding of near wall flows

whose knowledge is of vital practical importance in order to improve heat and mass transfer, while

minimizing friction drag, reducing aerodynamically caused noise. This research finds its application

in various areas such as ground transport and aeronautics. These studies are mainly based on

experiments, but numerical simulations are also performed through collaborations, especially within

the framework of joint supervision thesis.

The achievement of these objectives is made possible by large experimental facilities available at the

laboratory allowing accurate measurements featuring high spatial resolution around complex

geometries. These large dimension facilities are quite appropriate to provide an experimental database

to be used both to set up precise scaling of turbulent flows that keeps being a cause for considerable

controversy and to improve near wall turbulence models.

The group continues to pursue the development of the electrochemical method for the measurement

of the unsteady turbulent wall shear stress in complex flows by studying both theoretically and

experimentally the dynamic response of the electrochemical probes. This powerful tool permits to

complement standard measurement techniques (hot wire, LDA, PIV) for a better understanding of

physical phenomena that occur in the near wall regions. In this framework, we have recently started a

new project in collaboration with Prof. Stanislas (University of Lille) and his team. This project aims at

validating the numerical models for boundary layers with adverse pressure gradient including

separation.

The control of the flow around three-dimensional blunt bodies is another area of fundamental and

applied research initiated by this group two years ago. The main objective is to find the link between

complex separated structures and aerodynamic loads exerted onto the body. The main results

obtained up to now on this configuration are the aerodynamic drag reduction up to 9% by using a

passive control and the evaluation of the contribution of each term of the momentum equation to the

aerodynamic drag. We have demonstrated that the longitudinal vortices and turbulence have in fact a

significant contribution. Measurements of the unsteady wall shear stress using an array of

electrochemical probes inserted at the back side of the body are being performed. The first results

show that complex turbulent structures are successfully captured with this technique.

3 - Perspectives

The DF2T department research areas will be strongly oriented to the experimental and numerical

studies of the interactions between flows, heat and mass transfers. Our research developments will

focus on the convective heat transfers on rotating systems, impinging jet, confined and swirling flows,

control of the flow around three-dimensional blunt bodies, near wall turbulence models.

In the item of convective heat transfers on rotating systems, we will focus our efforts on the study of

the instabilities devoted in enclosed rotor-stator and co rotating disks in order to identify the influence

of flow structures on convective heat transfers, this using PIV, LDV, hot and cold wire anemometry

for flow dynamic measurements and PLIF for flow thermal measurements. For these projects we

participate to a Blank ANR International program, dedicated to fundamental research.

The behaviour of dynamic and thermal boundary layers in pulsating internal flows will be developed

using at the same time hot wire anemometry and cold wire thermometry. The aim is the

understanding of the effect of flow unsteadiness on the heat transfer. In particular, the results are

necessary for a better mastering of heat transfer of inlet and exhaust pipes of internal combustion

engines.

Our researches efforts will also focus on the study of internal swirling flows which allows the

enhancement of convective heat transfers in heat exchangers. The aim of the project is to get a deep

insight into the physics of internal swirling flows for a large range of Reynolds numbers, with an

approach combining numerical and experimental studies. For the experimental study the unsteady

wall shear stress will be precisely measured using the polarographic method, standard PIV and LDV

techniques for the flow field patterns. Concerning the numerical part, one of the objectives is to

"follow" the evolution of the intensity of the shear stresses thanks to an open source software, such as

OpenFOAM.

Within the framework of the operation Multi-physics and multi-scale approaches of braking of the CISIT

program, in close collaboration with the Laboratory of Mechanics of Lille, the department develops

research on the coupling between thermal physics and tribology. A two-color pyrometer with optical

fiber was designed and produced specifically for applications in braking, thus allowing obtaining the

temperature and emissivity in transient operation on the friction surface. Original tests consisting in

determining the local temperatures on the friction surface, while inserting in the pad the optical fiber

of the two-color pyrometer hitting the spot at friction surface through a fluorite window of small

diameter (transparent with infrared), will continue to be carried out.
