WebBoundary layer suction [1] is a boundary layer control technique in which an air pump is used to extract the boundary layer at the wing [2] or the inlet of an aircraft. Improving the air flow can reduce drag. Improvements in fuel efficiency have been estimated as high as 30%. The boundary layer [ edit] WebThe boundary-layer equations for two-dimensional incompressible flow are integrated numerically for the flow over a flat plate and a _ Howarth body. Injection is introduced either impulsively or period-ically along a narrow strip. Results indicate that injection perpen-dicular to the wall is transmitted instantly across the boundary layer inxlms.anglogoldashanti.com.au
