Environmental Engineers' Handbook, Second Edition
A wake that causes downwash usually occurs as the result of one of three
physical conditions: 1) the stack, referred to as stack-tip downwash, 2) local
topography, or 3) nearby large structures or building downwash. Figure 5.8.10
shows ...

We have seen that the downwash induced on an aft tail by the main wing has a
significant effect on the trim and static stability of an airplane. This downwash
reduces the effective angle of attack for the horizontal tail and also reduces its ...

Various stack shapes and their properties with regard to aerodynamic downwash
: (a) flared stack, poor design, pronounced stack downwash induced; (b) straight

To avoid stack -tip downwash, environmental engineers should consider the ratio
of emission velocity (vs) to wind speed velocity at the stack height (us) in the
stack design. If v, < 1.5 us, then the physical stack height should be adjusted by
the ...

Hiroshi Higuchi Syracuse University A simple water channel experiment shows
the phenomenon of tip vortices and downwash similar to that behind an aircraft
despite large differences in scaling parameters. In this study, a rectangular flat ...

The result of this wing vortex system is to induce a downward component of
velocity to the air flow, which is referred to as downwash. Actually, as shown by
Prandtl1 in his lifting line theory, the vortex is not restricted to the wing tips but
consists ...

These vortices are drawn downwards because their outbound side rubs against
the surrounding air masses and their inbound side is drawn downwards by the
wing's downwash. The downwash is used to explain the induced drag and
ground ...

In addition. the downwash angle for the flow at the wing location for an clliptically
shaped wing is predicted to be £w = CL/nA (9.27) II" the tail is fairly far behind the
wing, the downwash angle at the tail is theoretically about twice the downwash ...
