Convective boiling and heat transfer are studied experimentally in a vertical sintered fibrous channel heated on the walls. For given values of the operating parameters, several zones, corresponding to different fluid states, appear in the channel. A thermal non-equilibrium state between the liquid and its vapor is observed for critical operating conditions. The transition corresponds to a dry out of the heated wall. The heat transfer between the walls and the fluid is systematically studied. A boiling curve, taking into account the presence of a thermal nonequilibrium zone, is derived for the sintered porous channel.
