Aerodynamics of wing-assisted incline running in birds

BW Tobalske, KP Dial - Journal of Experimental Biology, 2007 - journals.biologists.com
Wing-assisted incline running (WAIR) is a form of locomotion in which a bird flaps its wings
to aid its hindlimbs in climbing a slope. WAIR is used for escape in ground birds, and the …

An overview of a Lagrangian method for analysis of animal wake dynamics

J Peng, JO Dabiri - Journal of Experimental Biology, 2008 - journals.biologists.com
The fluid dynamic analysis of animal wakes is becoming increasingly popular in studies of
animal swimming and flying, due in part to the development of quantitative flow visualization …

The comparative hydrodynamics of rapid rotation by predatory appendages

MJ McHenry, PSL Anderson… - Journal of …, 2016 - journals.biologists.com
