Tairov E.A. Method of measuring void fraction in a channel with porous media // Thermophysics and Aeromechanics. Vol.27. No.2. 2020. P.313-316. DOI: 10.1134/S0869864320020134 A new method is described for measuring the average void fraction of a one-component two-phase flow moving in a channel with a fixed porous aggregate. The known method of cutting off the flow is used but, in contrast, the vapor phase in the cut-off volume is transferred to the condensed state, and the released space is filled...

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...

Application of a Volterra quadratic polynomial to modeling elements of heat engineering devices // E3S Web of Conferences. Vol.114. ID: 01007. 2019. DOI: 10.1051/e3sconf/201911401007 This paper considers integral models built to describe dynamic processes in a 135 MW power unit condenser. For this purpose, we use a quadratic segment of the Volterra integral power series. The first set of models was built with a perturbation of the cooling water flow, and the second...
