Three dimensional turbulent boundary layers. A report on Euromech 33
Abstract
The contributions of 42 participants from six countries to the 1972 European Mechanics Colloquium in Berlin are summarized. Differential and integral methods for predicting three dimensional turbulent boundary layers are discussed as well as their relative merits. Experiments reported concern: (1) measurements on infinite swept wings and on a slender wing; (2) measurements made in the boundary layer of a 60 deg curved duct with straight entry and exit sections; (3) methods for measuring the boundary layer on a two meter reflex model of a large cargo ship at a Reynolds number of 5 x 10 the the 6th power in the air; (4) preliminary measurements of skin friction, mean and fluctuating velocities along the circumference and at several stations in the streamwise direction of the boundary layer in a symmetric annulus fitted with an asymmetric end plate; (5) turbulent boundary layers on the stationary or rotating hub of an annular duct with either zero or adverse pressure gradient in an axial or swirling outer flow; (6) flow visualization of wall streamlines in curved ducts, on rotating disks, turbine blades and on inclined cylinders; and (7) the effectiveness of three dimensional film cooling slots.
