THERMAL DIFFUSION AND CONVECTIVE STABILITY OF TWO COMPONENT FLUID IN A POROUS MEDIUM
要約
The effect of thermal diffusion on the convective stability of two component fluid in a porous medium has been investigated by the linear(normal mode) and non-linear (energy) theories, taking into account both Darcy and the usual viscous resistances in the momentum equation. The most important result is that a stability has been found which suppresses the convection current even when the density gradient is adverse (heated from below and salted from above). Also, since the linear and non-linear stability limits do not coincide, subcritical instabilities exist.
