1. Assuming an incompressible, inviscid flow with a uniform freestream as shown in the
figure below, tick which one of the following statements are true. (Note:
)
a.
b.
c.
d. Depends on the angle of attack
2. Determine the streamline shapes of the following inviscid 2D velocity field as follows: Solving this differential equation, we get: These represent equations of streamlines as circles of radius √ . 3. For the above field, evaluate the material derivatives
and
; and evaluate
the pressure gradient . Assume the flow is incompressible without body forces.
From the momentum equations in and direction (no viscous/body forces), we have:
( ) () ⃗ ⃗ ⃗ ⃗...
