A partial case of Phase Equilibrium with two fluid phases staying at Thermodynamic equilibrium.
In other words it's a state of thermodynamic equilibrium between the 2-phase region on PT Diagram where both liquid and gas state of a Fluid Mixture. The PT Diagram for Pure Substance will see Vapour Liquid Equilibrium (VLE) as a set of points along a smooth curve ending up with a Critical Point

The PT Diagram for Fluid Mixture will see Vapour Liquid Equilibrium (VLE) as a closed area Vapour Liquid Envelope is bounded by Bubble Point Curve and Dew Point Curve with a junction at at Pseudo-Critical Point Point
