- Phase equilibrium of CO2-brine fluids is important to studies related to CO2 sequestration in deep saline aquifers and CO2 enhanced oil recovery.
- Assessing the possibility of CO2 leakage is one of the major challenges for geological carbon sequestration.
- This article reviews the discovery of new phases of carbon (Q-carbon) and BN (Q-BN) and addresses critical issues related to direct conversion of carbon into diamond and h-BN into c-BN at ambient temperatures and pressures in air without any need for catalyst and presence of hydrogen.
- The cooling heat transfer of supercritical carbon dioxide (CO2) remains an issue unsolved, into which many experimental and formulating investigations were performed.
- Extended Abstract A fluid above its critical temperature and pressure (Pc, Tc) is called supercritical (SCF) under which conditions the distinction between liquid and gas phases no longer exists.
- In the supercritical phase, pure fluids have great potential for industrial applications and are increasingly used by industry as nonpolluting solvents of organic materials and media for high yield chemical reactions.
- The basic problems associated with the transition to supercritical coolant pressure in water cooled reactors are outlined: the need for deeper study of the heat and mass transfer, especially that occurring during flow in complicated spatial structures, in order to develop reliable computational methods and materials for fuel-element cladding that are capable of operating at elevated temperature under the conditions of high corrosion activity of the medium; securing an acceptable degree of safety and increasing the economic efficiency of NPP with a reactor with supercritical coolant pressure.
- Mixed convection heat transfer between supercritical water and particles is a major basic problem in supercritical water fluidized bed reactor, but little work focused on this new area in the past.
