The purpose of the HyMPaCt project is to study the effects of different hypergravity levels on the thermal behaviour of a metal foam/paraffin wax composite, which can be used for the thermal management and the heat storage, both for space and ground applications, during its melting and solidification process.

The storage of thermal energy via phase-change-materials (PCMs) is particularly enticing as it provides benefits including the temperature control and the high thermal energy storage density. However, the PCMs are characterised by a relatively low thermal conductivity (around 0.4W/(m·K)), which does not allow high energy storage performance. The issue has been resolved using the high conductivity of Metal Foam.  In fact, it allows a larger fraction of the PCM to melt, increasing the energy storage performance. Metal Foam/Paraffin wax materials have not been investigated in hypergravity conditions.  They can be found in many technological fields, from automotive to aerospace as well as bio-medicals and  chemistry.  It is therefore important to understand how different gravity levels influence the thermal behaviour of these composite materials, in order to choose the best metal foam characteristics for each particular environment.
