Abstract In this paper, the investigation of pool boiling heat transfer on biphilic micro/nanostructured surfaces is presented. An array micrococoons from silicon oxide nanowires was synthesized surface a copper heater using gas-jet electron beam plasma chemical vapor deposition method. The properties were achieved by applying fluoropolymer spots hot wire deposition. Technology creating develop...

The paper presents investigations into pool boiling heat transfer for open minichannel surfaces. experiments were carried out with saturated ethanol at atmospheric pressure. Parallel microchannels fabricated by machining about 0.2, 0.3 and 0.4 wide 0.2 to 0.5 mm deep. measurements performed increasing flux variable geometric parameters of the minichannels. image acquisition speed was 493 fps (a...

The ̄ow boiling phenomenon over a heated tube restricted by an interference sleeve, which is a passive enhancement technique, has been analysed using a semi-empirical approach. The liquid boiled was water ̄owing through an annular cross-section. A model developed earlier for the case of pool boiling over porous surfaces has been adapted after modi®cation to pool boiling with interference surfac...
