Influence of heater size on critical heat flux in flat microchannels with intense localized heating [PDF]
E3S Web of Conferences, 2023 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]
E3S Web of Conferences, 2023 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]
Physical Review E, 2009 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,
