Unformatted text preview: EAS 4101 - Aerodynamics – Spring 2009 04/29/09, Final Exam Name: ____________________________________ 1 I. TRUE/FALSE (10 points total - 1 point each) Clearly circle T for true statements and F for false statements. 1. Flow in a boundary layer is irrotational if there is an adverse pressure gradient. T F 2. Ailerons are used to generate roll, which is a rotation about the longitudinal axis of an aircraft. T F 3. Streamlines, streaklines, and pathlines all have a time history associated with them T F 4. In fluid mechanics Gauss’ divergence theorem is used to transform a control surface integral into a control volume integral. T F 5. In an incompressible flow field, the velocity field is solenoidal. T F 6. A potential function exists only if the flow is 2-D, incompressible, inviscid, and irrotational. T F 7. The Kutta-Joukowski Theorem states that circulation and lift are directly proportional T F 8. The single horseshoe vortex in ideal flow obeys the Biot-Savart Law and the Helmholtz theorems T F 9. Increasing the “fullness” of the velocity profile (i.e. increasing the shape factor, H) reduces the shear stress seen at the no-slip boundary. T F 10. The kinetic energy of a fluid is the sum of the potential and internal energies. T F II. SHORT ANSWER: Answer all parts of the question to receive full credit. (35 total points) 11. Fluid motion can be kinematically decomposed into 4 types. List the 4 types of motion. For an ideal flow, which of the components will be non-zero? (4 points) EAS Name: __________________________ 12.
