WebThe momentum thickness, θ, is a theoretical length scale to quantify the effects of fluid viscosity in the vicinity of a physical boundary. Mathematically it is defined as (2.1) where … WebConcept: In flow over a flat plate, various types of thicknesses are defined for the boundary layer, (i) Boundary layer thickness (δ): It is defined as the distance from the body surface in which the velocity reaches 99 % of the velocity of the mainstream (U ∞) (ii) Displacement thickness (δ* or δ +): It is defined as the distance by which the body surface should be …
