Streamline Coordinates (62)
•
Some perspective on these results
•
sdirection
–
Decreasing velocity means increasing pressure and vice
versa
•
ndirection
–
Pressure increases in the direction outward from the
center of curvature of the streamlines
•
Remember this is inviscid flow

Hurricanes as Free Vortex (irrotational)
•
Our discussion of incompressible, inviscid flow doesn’t apply
to the eye, but outside of this region the flow can be modeled
as a free vortex (see example 5.6 in text)

6.27: To model the velocity distribution in a curved inlet
section of a wind tunnel, the radius of curvature of the
streamlines is expressed as R=LR
o
/2y. As a first approx,
assume the air speed along each streamline is V=20 m/s.
Evaluate the pressure change from y=0 to the tunnel wall at
