The thickness up to which the velocity approaches 99% of the free stream velocity. The distance measured perpendicular to the boundary by which the free stream is displaced on account of the formation of the boundary layer.

<h3>What is displacement thickness in boundary layer theory?</h3>

The displacement thickness for the boundary layer is defined as the distance the surface would have to move in the y-direction to reduce the flow passing by a volume equivalent to the real effect of the boundary layer.

The thickness of the boundary layer represented by δ is arbitrarily defined as that distance from the boundary surface in which the velocity reaches 99% of the velocity of the mainstream.
