Pool Evaporation at Higher Vapour Pressures

open access: yesChemical Engineering Transactions, 2016
Hazardous substances with a boiling point close to ambient temperatures will evaporate at higher vapour pressures, so that the evaporation takes places in the smooth transition between the evaporation at boiling point and below boiling point ...

The effect of tube diameter on vertical two-phase flow regimes in small tubes

open access: yes, 2006
Flow boiling flow patterns in four circular tubes with internal diameters of 1.10, 2.01, 2.88 and 4.26 mm were investigated in the present project. The experiments were conducted in vertical upward two-phase flow using R134a as the working fluid.

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

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.
