Dynamic transition in supercritical iron [PDF]
arXiv, 2014 Recent advance in understanding the supercritical state posits the existence of a new line above the critical point separating two physically distinct states of matter: rigid liquid and non-rigid gas-like fluid. The location of this line, the Frenkel line, remains unknown for important real systems. Here, we map the Frenkel line on the phase diagram of

Local structure of supercritical matter [PDF]
arXiv, 2014 The supercritical state is currently viewed as uniform on the pressure-temperature phase diagram. Supercritical fluids have the dynamic motions of a gas but are able to dissolve materials like a liquid. They have started to be deployed in many important industrial applications stimulating fundamental theoretical work and development of experimental ...

Deep Underground Science and Engineering, EarlyView.CO2‐enhanced oil recovery (CO2‐EOR) is an economically viable carbon capture, utilization, and storage (CCUS) technique that is widely practiced and contributes significantly to the achievement of carbon‐neutral cities. However, few studies have been conducted on CO2‐EOR source–sink matching involving different emission sources, different carbon ...

Microscale physics and macroscale convective heat transfer in supercritical fluids [PDF]
arXivDriven by fundamental thermodynamic efficiency considerations, an emerging trend in the energy and propulsion systems is that the working fluid operates at a pressure above the critical pressure. Energy transport is thus accompanied by dramatic and strongly nonlinear variations of thermophysical properties, which cause abnormal heat transfer behavior ...
