Approximate system of equations for describing nonstationary natural concentration convection in binary gas mixtures

Convection and heat/mass transfer processes under space flight conditions

“…For helping to found and develop this branch in the USSR, great credit must go to Academician V. S. Avduevskii 1 . In connection with this and other applications, we note the development of mass transfer models based on the compressible-gas equations with filtration of the acoustics [18], vibrational convection models (averaged flows induced by non-translational vibration [19]), numerical and experimental studies of low-frequency convection in the presence of vibration [20], the generalization of models of convection under the action of translational and non-translational vibration with account for various complex factors [21], etc.…”

“…In [38], analytical solutions of 3-D linear problems of this kind are presented. Due to the small time scale of acoustic disturbances, in several papers models with "filtration" of thermoacoustic disturbances have been developed for perfect [18,42] and imperfect [25,37,38] gases. We note that, in [41], the authors used the term "thermoacoustics" for the interaction of thermal gravitational convection with given acoustic disturbances, which is something different.…”

Mixing of two gases one of which is expelled from a cylindrical space by the other

“…In [5] the model proposed in [ll] was applied, in particular, to a :fluid enclosed between two infinite disks where its use is better justified.…”
