Effects of Cavitation on Rotordynamic Force Matrices [PDF]
, 1988 When designing a turbomachine, particularly one which is to operate at high speed, it is important to be able to predict the fluid-induced forces, both steady and unsteady, acting on the various components of the machine.

On the estimation of time dependent lift of a European Starling during flapping [PDF]
, 2015 We study the role of unsteady lift in the context of flapping wings in birds' flight. Both aerodynamicists and biologists attempt to address this subject, yet it seems that the contribution of the unsteady lift still holds many open questions.
