Synonym: Fluid Phase Equilibrium = Vapour Liquid Equilibrium (VLE)
A partial case of Phase Equilibrium of with two fluid phases, specifically: staying at Thermodynamic equilibrium.
In other words it's a state of Thermodynamic thermodynamic equilibrium between the liquid and gas state of a Fluid Mixture.

The PT Diagram for Fluid Mixture will see Vapour Liquid Equilibrium (VLE) as a closed area region (also called Vapour Liquid Envelope) bounded by Bubblepoint Curve and Dewpoint Curve with a junction at at Pseudo-Critical Point Point
