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 ...

Thermal Transients in District Heating Systems

Chertkov M., Novitsky N.N. Thermal Transients in District Heating Systems // Energy. Vol.184. 2019. P.22-23. DOI: 10.1016/j.energy.2018.01.049 Heat fluxes in a district heating pipeline systems need to be controlled on the scale from minutes to an hour to adjust to evolving demand. There are two principal ways to control the heat flux - keep temperature fixed but adjust velocity of the carrier ...
