laminar sublayer in a sentence

• This is necessarily nonzero because the turbulent velocity profile defined by the law of the wall does not apply to the laminar sublayer.
• Flow is defined as hydraulically smooth if they are smaller than the laminar sublayer ( and therefore ignorable by the main body of the flow ).
• For a near-wall laminar sublayer of thickness " ? ? " and a characteristic roughness length-scale " k s ",
• The distance from the wall at which it reaches zero is determined by comparing the thickness of the laminar sublayer with the roughness of the surface over which it is flowing.
• The laminar sublayer is important for river-bed ecology : below the laminar-turbulent interface, the flow is stratified, but above it, it rapidly becomes well-mixed.
• Intuitively, this means that if the roughness elements are hidden within the laminar sublayer, they have a much different effect on the turbulent law of the wall velocity profile than if they are sticking out into the main part of the flow.
• It's difficult to see laminar sublayer in a sentence .
