Hydrodynamic Forces and Torques for a Nonspherical Particle

Drag on an Axisymmetric Body

 Evaluation of the integral on the right hand side of (6) could become quite cumbersome. When the fluid is at rest at infinity, the flow field for a point force is given by

,   (7)

where

(8)

Since far from the particle, the effect of the particle is essentially equivalent to a point, it follows that

(9)

When the fluid is not at rest at infinity, (9) is replaced by
(10)
