0 relating to substances that are heated to higher than their critical temperature and pressure (= the highest temperature and pressure at which a gas can be changed into a liquid), resulting in changes to the way they behave: --
When the specifying flow is slightly supercritical, a weakly nonlinear solitary wave (29a) is possibie.
The flow is then supercritical and internal hydraulic jumps may occur under suitable downstream conditions.
Two-dimensional rolls have indeed been shown to be a stable bifurcation solution for weakly supercritical convection.
A similar analysis shows that these flows are also supercritical t o waves of that type.
There is no question of applying an 'initial' condition, in the sense that it is used in the case of disturbances under supercritical conditions.
The failure point is identified as the point where the profiles of the marginally subcritical and marginally supercritical initiation energies start to deviate significantly.
In both these investigations the heating was supercritical.
The supercritical, steady two-dimensional motion, the heat transport and the stability of the motion are investigated.
