DIEF Dipartimento di Ingegneria Industriale


Thermodynamics represents the main research subject of the group. In particular, the focus is on themes related to non-equilibrium thermodynamics, entropy production and heat transfer inside energy and refrigeration systems.


Currently, there are many thesis subjects available: 

  • Modeling of evaporator and condenser with pressure losses
  • Microchannel heat exchangers
  • Thermodynamic optimization of heat exchangers
  • District heating and cooling
  • Constructal Theory applications
  • Artificial Muscles
