Binary mixtures in linear convection arrays
WebBy (linear) convection array we mean here a stationary laminar flow with periodic stream function like c(x,y) of eqn (1), con-fined between two parallel edges, y = 0 and y = L/2, which act as dynamical reflecting boundaries. The unit cell of the array consists of two counter-rotating convection rolls [Fig. 1(a)]. WebAug 6, 2024 · This paper reports a fully developed thermo–solutal mixed convection flow of the binary mixture of some important chemical species and its linear stability characteristics in a vertical channel. The flow is jointly driven by an external pressure gradient as well as simultaneous buoyancy effects of thermal and chemical species …

WebIn order to interpret the results quantitatively, we determined the necessary thermodynamic and transport properties for six mixtures ~He-CO2, He-SF6, He-Xe, Ne-Ar, Ar-CO2, and H2-Xe! by a combination of data from the literature, molecular-theory calculations, and thermal-conductivity measurements. WebIn binary-fluid mixtures, such as ethanol and water, the temperature and concentration fields are coupled through the Soret effect, so that an externally applied temperature gradi- ent drives a mass flux. This results in a vertical concentration gradient which, in the presence of gravity, can stabilize or destabilize the quiescent fluid layer.
