FAQ

What is the Boundary Layer Thickness?
Boundary Layer Thickness is the distance normal to the wall to a point where the flow velocity has essentially reached the ’asymptotic’ velocity. Boundary Layer Thickness is usually measured using the Meter for Length. Note that the value of Boundary Layer Thickness is always negative.
Can the Boundary Layer Thickness be negative?
Yes, the Boundary Layer Thickness, measured in Length can be negative.
What unit is used to measure Boundary Layer Thickness?
Boundary Layer Thickness is usually measured using the Meter[m] for Length. Millimeter[m], Kilometer[m], Decimeter[m] are the few other units in which Boundary Layer Thickness can be measured.
