CRYSALIS acoustic tech at EUCASS 2025
Presented in Rome during the Space Exploration session
Lucas Leal and Ricard González-Cinca presented
Advancing cryogenic fluid control with acoustic waves
This week, the acoustic techniques developed within the CRYSALIS project were presented at the EUCASS conference in Rome by Lucas Leal and Ricard González-Cinca from the Universitat Politècnica de Catalunya (UPC).
Their presentation, titled “Bubble control in cryogenic fluids by means of an acoustic technique”, was delivered on Wednesday during the Space Exploration 1 session.
CRYSALIS is an EU-funded project aimed at developing the technologies for in-orbit storage and transfer of cryogenic propellants. The ability to control gas bubbles within the liquid using acoustic fields opens up promising techniques for boil-off control and the reduction of settling time — two critical aspects for advancing space exploration.
However, the behaviour of cryogenic fluids in microgravity is still not well characterised. Through modelling and simulation, the performance of these acoustic techniques can be analysed and optimised before in-flight experiments.
This work contributes to the CRYSALIS mission of enabling safer, more efficient, and sustainable cryogenic operations in space.
