In the second experiment, young researchers from the University of Brussels in Belgium and the University of Cambridge in the UK will investigate whether graphene can improve the efficiency of heat transfer in loop heat pipes. These are cooling systems used in satellites and aerospace instruments. A significant part of loop heat pipes is the wick – typically a porous metal material. The team will coat the wicks with graphene-related materials and test their efficiency during low-gravity parabolic flights. The experiment will be in collaboration with the National Research Council of Italy and Leonardo Spa in Italy, while the flights will be operated by ESA and Novespace in France.
