EAS 4101 - Aerodynamics – Spring 2004 3/3/04, Exam #1 Name: _____________ __________ 2/13 Questions continued: (45 points total, 3 points each, unless otherwise marked) 5. For inviscid flow around a bend, does the pressure increase, decrease, or remain the same in the outward direction from the bend (or radius of curvature is increasing)? 6. What are the conditions under which both the streamfunction and the velocity potential identically satisfy Laplace’s equation for a spherical coordinate system ? 7. In ideal flow, it is common to employ superposition solutions of various individual solutions to Laplace’s equation in terms of the streamfunction and/or velocity potential. Is it also valid to superimpose pressure fields of each individual solution? Please justify your answer mathematically and/or physically. 8. List and explain the origins of the two types of drag acting on a 2-D bluff body
