SHEAR FLOW PRODUCTION AND STAGNATION STREAMLINE DISPLACEMENT IN A SHEAR FLOW
Abstract
The production of shear flow profile in a wind tunnel test-section
with the aid of in-plain horizontal wire-grids is explained. The design
procedure with experimental results are given. It is concluded that the
deepest shear, produced by this procedure, cannot have a slope of more than
1.777. It is shown that the stagnation streamlines in a shear flow will
be displaced due to the existence of stagnation pressure gradient. The minimum
displacement is c function of pressure coefficient and the velocity profile,
which is confirmed by the experimental results.
