Critical heat flux density in diphasic thermosyphons [PDF]
The paper presents an analysis of known dependencies for determining the critical heat flux density in diphasic thermosyphons. The critical heat flux density for the created experimental model of thermosyphon were calculated on the basis of the ...

Influence of heater size on critical heat flux in flat microchannels with intense localized heating [PDF]
Experiments were carried out on flow boiling in mini- and micro- channels under local heating for different heater size. It was found that with an increase in the channel height in the range of 0.2–3.7 mm, the intensity of heat transfer and the critical ...

Modelling of pool boiling on the structured surfaces using Lattice Boltzmann method [PDF]
The process of boiling on spatially structured surfaces is simulated by a hybrid model based on Lattice Boltzmann Method and heat transfer equation. The model permits to study heat transfer at boiling in a wide range of surface superheats for different ...

Critical heat flux around strongly heated nanoparticles [PDF]
We study heat transfer from a heated nanoparticle into surrounding fluid, using molecular dynamics simulations. We show that the fluid next to the nanoparticle can be heated well above its boiling point without a phase change. Under increasing nanoparticle temperature, the heat flux saturates which is in sharp contrast with the case of flat interfaces,

For boiling heat transfer, it is important to improve both the critical heat flux and heat transfer coefficient. In general, the heat transfer coefficient is improved by promoting the nucleation of boiling bubbles on the heating surface.

Use of a thin liquid film moving under the action of gas flow in a mini-channel for removing high heat fluxes [PDF]
Intensively evaporating liquid films shear-driven in a mini- or micro-channel under the action of cocurrent gas flow are promising for the use in modern cooling systems of semiconductor devices.
