Whirl aerodynamic

Aerodynamic whirl. Although the mechanism is not clearly understood, it has been shown that aerodynamic components, such as compressor wheels and turbine wheels, can create cross-coupled forces due to the wheel motion. Figure 5-23b is one representation of how such forces may be induced.
