Question:

Repeat Prob. 15–39, except for an axisymmetric, rather than a two-dimensional, body. Compare to the two dimensional case. For the same sectional slice shape, which has the lower drag coefficient? Discuss.


Data from Problem 39

Generate a computational domain to study incompressible, laminar flow over a two-dimensional streamlined body (Fig. P15–39). Generate various body shapes, and calculate the drag coefficient for each shape. What is the smallest value of CD that you can achieve?
