PORE NETWORK MODELS FOR THE STUDY OF TRANSFERS IN THE POROUS WICK OF LOOP HEAT PIPES
ABSTRACT
This paper presents an overview of pore network models for the study of vaporization phenomena occurring within a porous wick in relation with loop heat pipes (LHPs). Pore network models are a powerful tool to study two-phase flows in a porous structure. These models are based on a representation of the pore space in terms of a system of sites (pores) connected by throats (constrictions). First developed for studying steady-state regimes, pore network models are now used for the study of transient regimes in relation with the start-up phase of LHP and changes in the applied heat load during normal operation. Some open problems are also discussed.
