Pool Boiling Heat Transfer of Ethanol on Surfaces with Minichannels

open access: yesEnergies
In this paper, the pool boiling of ethanol was analyzed. The experiments were carried out at atmospheric pressure. Heat transfer surfaces in the form of deep minichannels were made of copper.

Modelling pressure fluctuations during flow boiling in microchannels with inlet compressibility and resistance [PDF]

open access: yes, 2009
Confined bubble growth during flow boiling at low pressures in microchannels generates pressure fluctuations that may cause transient flow reversals that disturb the flow distribution in heat sinks formed of parallel channels joined by plena.

Simulations of microflows induced by rotation of spirals in microchannels [PDF]

open access: yes, 2008
In microflows where Reynolds number is much smaller than unity, screwing motion of spirals is an effective mechanism of actuation as proven by microorganisms which propel themselves with the rotation of their helical tails. The main focus of this study
