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

, 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.

Heat transfer characteristics of an emergent strand [PDF]

A mathematical model was developed to describe the heat transfer characteristics of a hot strand emerging into a surrounding coolant. A stable strand of constant efflux velocity is analyzed, with a constant (average) heat transfer coefficient on the ...

Experimental study on thermal-hydraulic performance of helically coiled tubes steam generator of lead-bismuth reactor

International Journal of Advanced Nuclear Reactor Design and Technology
The advantages of the helically coiled tube steam generator lie not only in its high heat transfer efficiency but also in its compact structure, which is initially used in Pb–Bi–SCO2 reactors, and its main function is to transfer the heat from the lead ...

Analysis of flow boiling heat transfer in narrow annular gaps applying the design of experiments method

Advances in Mechanical Engineering, 2015
The axial heat transfer coefficient during flow boiling of n -hexane was measured using infrared thermography to determine the axial wall temperature in three geometrically similar annular gaps with different widths ( s  = 1.5 mm, s  = 1 mm, s  = 0.5 mm).
