The classical laminar solution to the momentum equation was provided by Blasius for the case of a semi-infinite flat plate aligned with uniform … 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.
WebA Blasius boundary layer (named after the German fluid dynamics physicist Paul Richard Heinrich Blasius, 1883--1970) describes the steady two-dimensional laminar boundary layer that forms on a semi-infinite plate which is held parallel to a constant unidirectional flow.
