French-Australian International Emerging Action on Engineering

2018 – 2020

Check out NAMICO latest results here: Namico_Results


The IEA “NAMICO” (Natural and Mixed Convective mass transfer phenomena impacting solar building envelope performance in urban environment) is developed in partnership between the Centre d’Energétique et de Thermique de Lyon (CETHIL) UMR-CNRS 5008, Lyon, France, the University of New South Wales (School of Mechanical and Manufacturing Engineering) and the University of Sydney. It addresses the comprehension and the mastering of ventilated solar components such as double-skin facades, hybrid Photovoltaic/Thermal collectors, Building integrated solar chimney, … that generate energy.

Missions and research themes

This IEA project focusses mainly on natural convective phenomena generated in open domains. The configuration studied experimentally and numerically is a single channel submitted to homogeneous and inhomogeneous Uniform Wall Flux (UWF) boundary conditions. Moreover, an indoor reduced scale solar chimney experimental test rig coupled to a cubic cavity (modelling a dwelling zone) has been set up in order to focus on the effect of radiation exchanges (wall to wall and fluid medium participating) on natural flow development which is conditioning the energy efficiency of such building integrated solar systems. 


The scientific project is focused on flow and heat transfer control, and addresses 3 main subtopics with both experimental and modelling approaches :

  • Laminar-Turbulent transition indicators
  • Impact of the external thermal stratification on a transitional natural convection flow
  • Impact of radiation on the natural convection flow

French-Vietnamese International Research Project in New Composite Materials

Dr. Nadine Pébère

Dr. Tran Dai Lam



The IRP (LIA) FOCOMAT “Functional Composite Material” (started in 2013 and renewed in 2017) is managed by Dr. Nadine Pébère (CIRIMAT) in France and Dr. Tran Dai Lam (VAST) in Vietnam.

Missions and research themes

The project aims at developing new composites materials (bulk or thin films systems). The scientific program is divided in three axes:

  1. Development of greener organic coatings
  2. Electrodeposited biomimetic apatite coatings
  3. Polymer composites with reinforcing plant fibers

1. Development of greener organic coatings

Organic coatings are widely used to prevent corrosion of metallic structures because they are easy to apply and cost effective. Corrosion inhibitors are incorporated in organic coatings to provide active corrosion protection. In the past, chromates were the most commonly used inhibitive pigments. However, due to their high toxicity, many studies have been devoted to the development of more environmentally acceptable organic coatings. In this context, our project aims to incorporate non-toxic corrosion inhibitors in organic coatings via natural clays (montmorillonite – MMT or layered double hydroxides – LDH), acting as nano-reservoirs for green inhibitors. The complementary effects of MMT and LDH on the microstructure of the coatings are investigated to search for synergistic effects by using different inhibitors. The study of the inhibitor leaching from the clays and their healing action in the case of damaged coatings will be specifically considered.

2. Biomimetic apatite coatings

A proper design of a bone implant material is aimed to provide the necessary durability, functionality, and biological response for long-term use. In this context, metallic materials, among which stainless steels, are most commonly implemented for load bearing implants. Durability and functionality of the implant are governed not only by the mechanical properties of the bulk material but also by the biological response, i.e. osteointegration that depends mainly on the surface/chemical characteristics of the implantable device. The challenges for electrodeposited coatings are twofold: (i) to be able to co-dope the apatite coating and to control the release kinetics and (ii) to produce coatings in lattices structures made from additive manufacturing (3D approaches), that is becoming the most usual method to produce the implants.

 3. Polymer composites with reinforcing plant fibers

The tailoring of polymer composites with long reinforcing plant fibers is a major issue of research in the domain of structural organic composite. The main advantage of such materials is weight saving. The other issue is to design recyclable materials. This explain that the choice must be restricted to linear polymers i.e. thermoplastics. Now, the difficult point is to be able to make the processing at a temperature that is sufficiently low for avoiding the degradation of the plant fiber. Finally, we focus on biosourced polymers. The reinforcing long fibers are bamboo fibers growing in North Vietnam: Dendrocalamus barbatus. The major interest of bamboo fiber is to possess the highest Young modulus among vegetal fibers. The first keys point is to define a treatment allowing the handling of the fiber during the processing of the composite. Moreover, it must allow a satisfactory interface with the polymeric matrix: the interfacial region is insuring the stress transfer from the matrix to the reinforcing fiber.

The GEODESIC (Geometry-Driven Signal and Image Processing) lab conducts research in the field of data science, with emphasis in signal and image processing applications. Specifically, researchers at GEODESIC develop new methodologies that take into account the geometry of the datasets and of the ambient space they live in.

Missions and research themes

The research themes of GEODESIC are the following:

– Topic 1: Adaptive Signal Processing on Manifolds

This reserach topic focuses on adaptive signal processing on manifolds. Precisely, it aims to
provide a comprehensive framework, describing the complexity and performance of adaptive algo-
rithms on manifolds. Currently, in the field of signal processing, adaptive algorithms on manifolds
are mostly considered heuristically, and on a case-by-case basis. the work at GEODESIC is to provide users with comprehensive guidelines for the design of efficient adaptive algorithms especially designed for processing data belonging to manifolds. Adaptativity is a key ingredient in many applications (pose or attitude estimation, localization, etc.) and manifold valued datasets are numerous. A timely challenge is to propose algorithms which are both adaptive and constrained to live on manifolds.

– Topic 2: Non-Commutative Signal Processing

In recent years, the signal and image processing community, and in a wider sense the engineering
community, has faced an increasing number of problems involving non-commutative algebraic
structures and manifolds. Signals and images taking their values on structures such as spheres
(Cosmic Microwave Background, probability density functions of multiple scattering processes,
…), rotation groups (attitude of rigid-body, polarized signals subject to geometric phase …), Stiefel
manifolds (partially observed attitude, subspace and array processing …) are now encountered on
a daily basis. Firstly approached by adaptation of standard methods, the community soon realized
that new paradigms should be adopted to tackle the non-linear problems faced with the processing
of such signals and images. It is now largely admitted that systematic use of differential geometry
and representation theory should be made, even though this is not exactly the case in practice.
This research topic inside GEODESIC proposes to develop new algorithms dedicated to signal
processing problems strongly related to the geometry of the space in which signals evolve.

– Topic 3: Information processing in sensor networks

The first two topics of GEODESIC are dedicated to signal indexed by (and/or living in) manifolds.
The third topic concentrates on discrete indexation sets: It concerns signals indexed by graphs,
hereafter designated as graph signals.
Graph signals are ubiquitous in our technological world. They are acquired in many applications
ranging from meteorology to neuroscience. They can be obtained from active sensor networks
(meaning that sensors process information and communicate with each other) or from passive
monitoring systems (like ElectroEncephaloGraphy–EEG– recordings). Furthermore, they are at
the heart of massive data sets and high dimensional statistics. For example, high resolution EEG
recordings deliver high temporal resolution signals living in dimension as high as 300. In neuro-
science, next generation imaging systems are likely to deliver high space-time resolution measure-
ments: In a few years, filming the activity of a whole neural networks will be possible.
Researchers at GEODESIC work on the design of inference algorithms for graph signal processing, with targeted applications such as neuroscience.
