EAS 4101 - Aerodynamics – Spring 2011 1/1 HW#3 1/26/11, 4 th Homework 1. Problem 3.5 from Bertin’s “Aerodynamics for Engineers”. 2. Problem 3.6 from Bertin’s “Aerodynamics for Engineers”. 3. Problem 3.11 from Bertin’s “Aerodynamics for Engineers”. 4. Problem 3.14 from Bertin’s “Aerodynamics for Engineers”. 5. Problem 3.15 from Bertin’s “Aerodynamics for Engineers”. 6. Problem 3.18 from Bertin’s “Aerodynamics for Engineers”. 7. Compare a potential vortex of strength 0 , 0 v 2 r  to another vortex defined as v r  , where is a rotational speed. Sketch the velocity profiles. Discuss whether or not the flows are well behaved for all r . Compute the vorticity fields and compare them. Are the flows irrotational everywhere? Do the flows possess any strain rate or shear stress? What is  and are viscous forces important?
