Résumé : The aim of this work is to model the phenomena of transport of matter, momentum and energy within a heat pipe, starting from the equations of continuity, Navier-Stokes and heat transport. This multilevel study consists of a local approach and a global one. On the one hand, the local approach allows to establish the profiles along the heat pipe for the height of liquid, the mean velocity of the flow and the temperature. This local study also highlights the influence of the parameters of the heat pipe on its performances. On the other hand, the global approach leads to the closure of a system of equations for the averaged values (on a cross-section of liquid) of the velocity of the flow, the pressure and the temperature of the heat pipe.
