Effect of the flow velocity on bubble boiling characteristics

Anatoliy L., Polina K. Effect of the flow velocity on bubble boiling characteristics // E3S Web of Conferences. Vol.128. ID: 06002. 2019. DOI: 10.1051/e3sconf/201912806002 The present research considers the initial stage of nucleate boiling with high heat fluxes releasing from the technical surface. We show new experimental data on the dynamics of the vapor phase in subcooled water flow in the channel under nonstationary heat release conditions. The heat release dissipation on the heater was performed...

On modeling of the initial stage of nonstationary nucleate boiling for the high heat fluxes

Levin A., Khan P. On modeling of the initial stage of nonstationary nucleate boiling for the high heat fluxes // MATEC Web of Conferences. Vol.240. ID: 01018. 2018. DOI: 10.1051/matecconf/201824001018 During recent years, there have been made significant achievements in the numerical description of the bubble boiling, particularly, in the calculation of the bubble growth dynamics, the nucleation density, and the bubble boiling threshold [1, 2]. However, the numerical prediction is mostly based on...

Verification of the heat transfer model for screw reactor

Levin A., Kozlov A., Svishchev D., Penzik M. Verification of the heat transfer model for screw reactor // MATEC Web of Conferences. Vol.240. ID: 05017. 2018. DOI: 10.1051/matecconf/201824005017 At present, the screw reactor pyrolysis is a promising and rapidly developing technology, because it helps obtain the end product, which is charcoal, tar, and synthesis gas. Additionally, pyrolysis can be considered as a preliminary stage for making the charcoal of the preset conversion for its further gasification...
