Evaluation of supercritical cryogen storage and transfer systems for future NASA missions [PDF]

open access: yes
Conceptual designs of Space Transportation Vehicles (STV), and their orbital servicing facilities, that utilize supercritical, single phase, cryogenic propellants were established and compared with conventional subcritical, two phase, STV concepts.

Supercritical multicomponent solvent coal extraction [PDF]

open access: yes, 1983
The yield of organic extract from the supercritical extraction of coal with larger diameter organic solvents such as toluene is increased by use of a minor amount of from 0.1 to 10% by weight of a second solvent such as methanol having a molecular ...

Nested subcritical flows within supercritical systems [PDF]

open access: yes
In supercritical systems the design inlet and outlet pressures are maintained above the thermaodynamic critical pressure P sub C. Designers rely on this simple rule of thumb to circumvent problems associated with a subcritical pressure regime nested ...
