Thickness definition
Web17 Nov 2024 · Boundary Layer Thickness. We define the thickness of the boundary layer as the distance from the wall to the point where the velocity is 99% of the “free stream” velocity. For laminar boundary layers over a flat plate, the Blasius solution of the flow governing equations gives: where Rex is the Reynolds number based on the length of the plate. WebAs the Reynolds number is less than the critical Reynolds number, thus the flow is laminar. The boundary layer thickness for the laminar flow is given by, δ = 4.91x √Rex δ = 4.91 x R e x. δ = 4.91 × 0.4 √2 × 105 δ = 4.91 × 0.4 2 × 10 5. δ δ = 0.00439 m. 2] The air is flowing over a flat plate at the velocity of 3 m/s.
