Design and manufacture a complex core structure accordingly and well adapted
to the inner thermal phenomenon seems to be a promising way to increase
performances.

Accordingly, NATHENA project aims at developing new complex inner structures
for heat exchangers.

NATHENA project will focus on the design development of a complex compact heat
exchanger that best addresses thermal performance, made by additive
manufacturing.

These new compact air-air heat exchangers developed in NATHENA project will
provide an efficient thermal management system dedicated to hybrid propulsion
system.

Two types of material will be studied regarding heat exchanger use: Aluminum
for low temperature range and Inconel for high temperature range.

The set objectives (see targets below) will be reached using calculation and
multi-physical simulation (thermomechanical-fluidic) applied to evolutionary
latticed and thin-walled structures combined optionally with fins to form a
matrix of complex structures.

Predictive models and/or laws will be developed for pressure and temperature
drop.

Topological and parametric optimization will be carried out in an iterative
way towards the most efficient model.

Through sample tests and final element method, calculation correlations will
be carried out to ensure the relevance and validity of the basic structural
choices as well as their combinations.

_Targets_ :

  * Delta temperature: 200°C to 400°C 

  

  * Flow: 0.01kg/s to 2kg/s 

  

  * Power: 0.5 to 500kW 

  

  * Reynolds number: 400 to 10000 

  

  * Pressure drop: 100mBar max 

  

  * Size: up to 500x300x300mm

by:

TEMISTH is working on new kind of heat exchanger produced by additive
manufacturing and/or coupled with traditional processes. Our skills are based
on thermal modeling of heat transfer (convection, diffusion, radiation and
chemical reaction) coupled with fluid flow (turbulence), heat exchanger design
(technology review, sizing, innovative materials) and thermal
characterization. We propose to our customer to reduce the conception and
prototyping cycle using our own innovative design tools that allow generating
in a short period a pre-design that can be used for fast prototyping and test
to make a proof of concept and analyze it. At this step we propose a new cycle
of conception to generate the best and customized design at high readiness
level.

The industrial fields in which we operate are numerous: Aeronautic,
Aerospatiale, Transport, Oil &

Gaz, Electronics

Entity Description : The von Karman Institute for Fluid Dynamics has been
founded in 1956 by the Professor Theodore von Karman as an international
Centre combining education and research for citizens of NATO countries within
its motto “High-Level Training in Research by Research". The IVKDF offers the
following educational programs: Lecture Series / Short Courses / Colloquia,
Short Training, University Master Thesis, Research Master in fluid dynamics,
Doctoral Program and Applied Research Program.

The VKI undertakes and promotes research on experimental, computational and
theoretical aspects of liquid and gas flows in the fields of the aeronautic,
aerospace, turbomachinery, environment and industrial and safety processes.
About fifty different specialized test facilities are available, some of which
are unique or the largest in the world. Research is carried out under the
direction of the faculty and research engineers, sponsored mainly by
governmental and international agencies as well as industries.

The IVKDF activity in the field of heat transfer has been and continues to be
rich. It includes

applications to aeronautics/aerospace, turbomachinery and industrial
processes. It concerns both the organization of international events and
fundamental and applied researches. As examples, one can quote the following
thematic areas:

· Thermal storage in packed beds

· Design of fluidized bed heat exchangers

· Thermohydraulics phenomena in saturated active porous media

· Heat pipe heat exchangers

· Ribbed heat exchangers

· Impinging-jet heat exchangers

· Engine Bypass Flow Heat Exchangers

· Tubular heat exchanger for hydraulic mockup

· Air/Hydrogen precooler heat exchanger · Multi-roll heat exchanger

To carry out such studies, optical measurement techniques relying on the
liquid crystal and more particularly infrared thermography have been
developed, sometimes in tough operating conditions. A state of the art of the
IR thermography application to IVKDF studies is proposed in the paper
“Convective Heat Transfer and Infrared Thermography (IRTh)” by Buchlin, J.-M.

#  3\. Phase 2 – STORAGE, SHARING, PROTECTION AND DISSEMINATION DURING THE
PROJECT

##  3.1 GENERAL INFORMATION ON THE DATA

As a reminder, this project is an industrial project. The data and results are
intended to lead to results that will be exploited by the scientific
coordinator according to the rules set out in the consortium agreement and in
the implementation agreement.

However, by mutual agreement between the partners and the scientific
coordinator, we have chosen to share some results by proposing public reports
that will provide information on the scientific process without giving
quantitative information.

The intellectual property concerning the data is managed in the implementation
agreement and the consortium agreement.

The project will draw on the experience and expertise of each partner and the
input data provided by the scientific coordinator.

Each dataset manager will be responsible for providing other partners with
data in formats that are neutral or compatible with the software provided for
the project.

The type and nature of data will be produced according to the following items:

  * Numerical simulations and design: the principal software used for these steps are CATIA V5, Star-CCM+, ANSYS Fluent, Patran/Nastran, Excel for spreadsheets, WORD for reports. These data will mainly be generated by SOGECLAIR aerospace SAS and TEMISTH according to their respective project data management procedures. 

  

  * Preparation of manufacturing and manufacturing: these data will be managed and generated according to the internal procedure of ADDUP. 

  

  * Development of test fixture and testing implementation: these data will be managed and generated according to the internal procedure of the Von Karman Institute for Fluid Dynamics. 

  

##  3.2 STORAGE AND SHARING DURING THE PROJECT

The generation, management and protection of data will be managed by each
partner according to its internal quality-security procedures.

In order to harmonize file names and ensure better version tracking, a file
naming procedure has been defined and shared between partners.

##  3.3 RISKS, SECURITY, DATA ETHICS

The main risks identified are data loss and non-respect of confidentiality.

In order to manage the risks inherent in data security, rules on the
publication of data have been defined in the consortium agreement and in the
implementation agreement validated by all partners. In addition, data exchange
between partners is organized through the use of a dedicated and secured
platform.

Given the data that will be generated during the project, the project does not
raise ethical issues.

##  3.4 DISSEMINATION AND ARCHIVING

As a reminder, this project is an industrial project. The data and results are
intended to lead to results that will be exploited by the scientific
coordinator according to the rules set out in the consortium agreement and in
the implementation agreement.

Apart from the specific market defined in the implementation agreement and in
accordance with the rules enacted in the consortium agreement, the data and
results generated by the Nathena project may be used by the partners to
propose new products or new innovative developments in various markets.
