Thermal characteristics and flow patterns of oscillating heat pipe with pulse heating

Experimental investigations of dynamic fluid flow in oscillating heat pipe under pulse heating

“…A brief summary of characteristic of each pattern will be given in this section. For more details, readers are referred to our previous work [22]. In our previous work [22], we also discussed "semi-annular flow" pattern.…”

“…For more details, readers are referred to our previous work [22]. In our previous work [22], we also discussed "semi-annular flow" pattern. Because "semi-annular flow" pattern is a transitional pattern, which is not that important and also is difficult to be defined during our data processing, such kind of flow pattern will not be further employed here.…”

“…utilizing check valve [18,19], nano fluid [20], acoustic cavitation [17,21] and pulse heating [22,23]. For some special applications (e.g.…”

“…Three different kind of flow patterns i.e. bubbly flow(Fig.2a-c), vapor-column (or plug[22]) flow(Fig.2d), annular flow(Fig.2e-f) have been identified with the variations of heating…”

Enhancement of heat and mass transfer by cavitation

“…When OHP operated, a self-sustaining oscillatory flow will be generated inside OHP, during the cycles of which the heat is transferred mainly as latent heat. In the past decade, the features of OHP has been intensively studied both experimentally [56][57][58] and numerically [59][60][61]. Recently, the effects of acoustic field on the performance of OHP have attracted much attentions [62,63].…”
