Impact of non-ideal transport modeling on supercritical flow simulation
The simulation of a supercritical fluid flow requires sophisticated models for real gas thermodynamic and non-ideal phenomena. They both are presently addressed through the simulation of a non-reacting and reacting high pressure H2/O2 splitter-plate ...

Experimental Study on Critical Flow of Supercritical CO2 at Steady State and Model Verification
When the loss of coolant accident happens in a reactor, because of the high temperature and high pressure in the reactor and the low external pressure, the critical flow may occur at the break due to sharp depressurization and vaporization.

Analysis of numerical studies on the thermal-hydraulic and neutronic thermal-hydraulic stability of supercritical water reactors [PDF]
The paper presents a review of modern studies on the potential types of coolant flow instabilities in the supercritical water reactor core. These instabilities have a negative impact on the operational safety of nuclear power plants.

The critical transition of Coulomb impurities in gapped graphene [PDF]
The effect of supercritical charge impurities in graphene is very similar to the supercritical atomic collapses in QED for Z > 137, but with a much lower critical charge.

Regeneration of Modified Bentonite Loaded with Phenol Using Supercritical Fluids
The desorption of phenol from organically modified bentonite (ODTMA–bentonite) using supercritical fluids was studied. Parameters such as pressure, temperature, supercritical fluid flow rate and co-solvent (entrainer) concentration were investigated. The
