Supercritical fluid — A supercritical fluid is any substance at a temperature and pressure above its thermodynamic critical point. It can diffuse through solids like a gas, and dissolve materials like a liquid. Additionally, close to the critical point, small changes… … Wikipedia
Supercritical carbon dioxide — Carbon dioxide pressure temperature phase diagram Supercritical carbon dioxide is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure. Carbon dioxide usually behaves as a gas in air at STP… … Wikipedia
Supercritical water reactor — The Supercritical water reactor (SCWR) is a Generation IV reactor concept that uses supercritical water as the working fluid. SCWRs are basically LWRs operating at higher pressure and temperatures with a direct, once through cycle. As most… … Wikipedia
Copper-chlorine cycle — Simplified diagram of the Copper Chlorine cycle The copper chlorine cycle (Cu Cl cycle) is a four step thermochemical cycle. It has a maximum temperature requirement of about 530 degrees Celsius.[1] The Cu Cl cycle is one of the prominent… … Wikipedia
Pressure-fed cycle (rocket) — The pressure fed cycle is a class of rocket engine designs. A separate gas supply, usually helium, pressurizes the propellant tanks to force fuel and oxidizer to the combustion chamber. To maintain adequate flow, the tank pressures must exceed… … Wikipedia
Transcritical cycle — A transcritical cycle is a thermodynamic cycle where the working fluid goes through both subcritical and supercritical states. This is often the case when carbon dioxide, CO2, is the refrigerant.The modern transcritical cycle was developed in… … Wikipedia
