The highly relevant journal Experiments in Fluids has just published a special feature issue on Animal Flight, which contains a multitude on cutting edge papers on animal flight. Among them are two papers from the CAnMove Flight Lab, one on analytical approaches for analyzing PIV(PIV = Particle Image Velocimetry) data and one on time resolved wakes from two species of bats flying in the wind tunnel (using our new high speed stereo PIV system). PIV has become a common approach of analyzing the aerodynamic "footprints" of flying animals, as the wake contains information about the magnitude and time-history of the aerodynamic forces generated by the flapping wings. The special feature also contains papers from other research groups, including other bats, hummingbirds, as well as more engineering oriented studies of heaving airfoils (but still of interest to the aerodynamics of animal flight). Experiments in Fluids focuses in new or improved methods of measuring flow properties, which captures the essence of research progress, i.e. the development of new techniques of observing or measuring nature, and is therefore a journal at the top of our list!
