Which outcome occurs when a supercritical fluid is rapidly decompressed across a turbine?

A)Adiabatic cooling with Joule-Thomson effect
B)Isothermal expansion near critical point
C)Increased fluid dynamic boundary instability
D)Formation of a distinct liquid phase

💡 Explanation

Rapid decompression causes adiabatic cooling due to minimal heat transfer and the Joule-Thomson effect, cooling the fluid rapidly because the enthalpy remains constant leading to a temperature drop; therefore, phase transition can occur rather than remaining a gas or forming liquids instantly.
