“…В работах [32][33][34] представлены результаты теоретического анализа теплофизическиз процессов при кипении наножидкости. Математическая модель течения и теплообмена при кипении наножидкости на плоской обогреваемой поверхности учитывает броуновскую и термофоретическую диффузии, влияние концентрации наночастиц в жидкости.…”

“…The used model assumes a uniform distribution of nanoparticles. Avramenko et al [9] studied the nanoparticles effect in motionless film boiling. The analytical results showed that the increase of nanoparticles concentration promotes heat and mass transfer.…”
The main purpose of this study is to survey numerically comparison of two-phase and single-phase models of heat and mass transfer of Al2O3-water nanofluid liquid film flowing downward a vertical channel. A finite difference method is developed to produce the computational predictions for heat and mass transfer during the evaporation of the liquid film approached by the single-phase and two-phase models. The model solves the coupled governing equations in both nanofluid and gas phases together with the boundary and interfacial conditions. The systems of equations obtained by using an implicit finite difference method are solved by Tridiagonal Matrix Algorithm. The results show that the two-phase model is more realistic since it takes into account the thermophoresis and Brownian effects.
“…During the last years, heat transfer enhancement in nanofluids, both in one-and two-phase flows, has been quite intensively studied both experimentally [5][6][7][8] and theoretically [9][10][11][12][13]. * Corresponding author.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
