Experimental study on the heat transfer enhancement in a rectangular channel with curved winglets
Experimental heat transfer, 2021Effects of the curved winglet vortex generator inserts (CWVGs) on the forced convection heat transfer, friction factor, and performance evaluation criteria (PEC) interior flow were experimentally examined in this work.

Nanowires for Enhanced Boiling Heat Transfer
Nano Letters, 2009Boiling is a common mechanism for liquid-vapor phase transition and is widely exploited in power generation and refrigeration devices and systems. The efficacy of boiling heat transfer is characterized by two parameters: (a) heat transfer coefficient (HTC) or the thermal conductance; (b) the critical heat flux (CHF) limit that demarcates the transition

Capillary Flow-Driven Heat Transfer Enhancement
Journal of Thermophysics and Heat Transfer, 2011DOI: 10.2514/1.T3747 Capillary flow in a microgroove for heat transfer enhancement is investigated. Competing effects of capillarity, wall shear,andavailable area forthe liquid flow determine the critical (maximum) heat transport capacity.A model for fluid flowandheattransferinthemicrogrooveofaV-shapedcrosssectionisdeveloped,andananalyticalsolution of ...

Heat transfer evaluation of an enhanced heat transfer tube bundle
Energy, 2014Abstract Demands to increase performance of modern heat exchange systems are constantly being made. Typical requirements include the removal of larger amounts of energy or the development of process units that occupy a smaller unit footprint. Vipertex™ 1EHT enhanced surfaces have been designed and produced through material surface modifications in ...

Heat Transfer of Two-Phase Impinging Jet: Heat Transfer Enhancement
Heat Transfer, Volume 2, 2004To study the enhancement and degradation mechanism of impinging two-phase heat transfer, air/water two-phase jet was applied on the cooling of copper surface of 30 mm in diameter. The two-phase jet impinged vertically on the horizontal heat transfer surface from capillary nozzle holes of 2, 4 and 6 mm in inner diameter.
