In physics and fluid mechanics, a Blasius boundary layer describes the steady two-dimensional laminar boundary layer that forms on a semi-infinite plate which is held parallel to a constant unidirectional flow.

What is Blasius equation formula?

f‴(y)+f(y)f″(y)=0. This equation is named after the German fluid dynamics physicist Paul Richard Heinrich Blasius (1883--1970), a student of Ludwig Prandtl (1875--1953), who provided a mathematical basis for boundary-layer drag.

What is the Blasius equation a solution for?

3.2.

1. Integrating the velocity profile determined by Blasius, the displacement, momentum, and energy thicknesses can be determined. We use the Blasius solution for the laminar boundary layer over a flat plate to estimate the boundary-layer thickness and skin-friction drag for the miniature wing from Example 3.1.
