MAE 3241: Aerodynamics and Flight Mechanics
Assigned: February 11, 2011
Homework #3
Due: February 28, 2011
Complete the following problems from the Fundamentals of Aerodynamics
:
3.11
3.12
3.15
Also complete the following questions:
Question 1:
Find the stream function and plot some streamlines for the combination of a line source,
Λ
, at (x,y)=(0,a) and an equal line source located at (0,a)
Question 2:
Find the stream function and plot some streamlines for the combination of a
counterclockwise line vortex with strength
Γ
at (x,y)=(a,0) and an equal line vortex
placed at (a,0).
Question 3:
A tornado is simulated by a line sink
Λ
=1000 m
2
/s plus a line vortex
Γ
=1600 m
2
/s. Find
the angle between any streamline and radial line, and show that it is independent of both r
and
θ
. If this tornado forms in sealevel standard air, what is the local pressure and
velocity 25 meters from the center of the tornado?
