The experiments of nucleate boiling heat transfer from porous surfaces were conducted in a pool of saturated R-11. The system pressure was varied in the range of 0.04-0.48 MPa. The porous structure in this investigation is composed of internal cavities in the form of tunnels, small pores, and small ribs under the pores. Compared to the performance of the previously developed surface, the new surface yields a marked enhancement of heat transfer at wall superheats of less than 2K and at a low system pressure of 0.04 MPa. Also reported is the importance of the size of the ribs which are designed obstruct the flooding of tunnels by incoming liquid.
