PHP2 - Pulsating Heat Pipes for Hybrid Propulsion systems
Overview
Objectives:
As part of H2020 program, Clean Sky 2, the present topic is associated within WP1.6 “Demonstration of Radical Aircraft Configurations” and more specifically subWP1.6.2 “Hybrid Power Bench Development and Testing”. It aims at using Pulsating Heat Pipes (PHP) to exchange large amounts of energy for the cooling of different elements.
The solution proposed here is to develop a very detailed 1D simulation code for the development of new PHP designs:
- fabricate them with innovative manufacturing techniques and extensively test them experimentally
- as a “proof-of-concept” of this new disruptive cooling technology. Experimental data is used to validate the 1D code and develop a reduced model
- that can be run in a short time (< 1s) to choose/select the most appropriate one for the application at hand.
This approach will make PHP commercially viable by cutting the time for their choice, sale and cost whilst eliminating all (or most) of the final testing by the end client.
Methodology:
Technical challenges are numerous due to an incomplete understanding of PHP in the literature: the lack of good design theories and of viable, comprehensive simulation tools to describe the thermal/hydraulic performance of a PHP. Furthermore, PHP are a new disruptive cooling technology that need to gain their acceptance into engineering practice…hence the partners need to carefully and thoroughly develop a very convincing case for their acceptance.
The present proposal, called P(HP)2 project, offers cooperation between JJ Cooling Innovation and Provides, leaders in modelling, design and fabrication of high-performance micro-two-phase cooling systems, and Altran, world-leader in Engineering Solutions and outsourced R&D, through their Expertise Centres “Fluids and Thermal Engineering” and “Scientific Computing Methods and Tools”.
