Description

Zhou Linjie fluid system for a turbine engine The present application is a divisional application of patent application filed on day 03 and 06 of 2023, with application number 202310203708.6 and the application of "Zhou Linjie fluid system for turbine engine". Technical Field The present disclosure relates generally to monitoring and controlling Zhou Linjie (PERICRITICAL) phase properties of fluids, including supercritical fluids and near supercritical fluids. More particularly, the present disclosure relates generally to Zhou Linjie fluids for use in connection with engines, such as turbine engines, including thermal management systems and fuel systems that use Zhou Linjie fluids. Background Engines such as turbine engines may use Zhou Linjie fluids for various purposes. Such peri-critical fluids may be used when near-supercritical or supercritical phases are present. For example, zhou Linjie fluids may be used in near-supercritical or supercritical conditions to cool various fluid flows or components of the engine. As another example, the engine may use fuel having a circumferential state of criticality (such as near-supercritical or supercritical phase). One or more operations of the engine may be affected by the phase of such a peri-critical fluid. For example, the engine may be configured for Zhou Linjie fluid used in Zhou Linjie phase (such as in near-supercritical and/or supercritical phase). Additionally or alternatively, one or more operations of the engine may be affected by a change in one or more phase properties of the Zhou Linjie fluid (such as a change corresponding to a phase change of the Zhou Linjie fluid and/or a change that may occur within a corresponding phase state of the Zhou Linjie fluid).
