Summary
New Additive manufacTuring Heat ExchaNger for Aeronautic
Today’s technologies and processes dedicated to the exchangers manufacturing hamper progress on higher performances (mechanical assies of repetitive and regular unitary components like folded sheet metal and/or tubing mostly welded).
Traditional manufacturing entails limit for the customization of the inner structure, which have a direct impact on the thermal behavior of the exchanger core.
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: Aluminium 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 (thermo-mechanical-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
