Hawkmoth flight stability in turbulent vortex streets [PDF]
, 2013 SUMMARY Shedding of vortices is a common phenomenon in the atmosphere over a wide range of spatial and temporal scales. However, it is unclear how these vortices of varying scales affect the flight performance of flying animals. In order to examine these

F IS FOR FALCON: THE TRUE STORY OF THE ‘NOVELLE’
German Life and Letters, Volume 79, Issue 3, Page 311-322, July 2026.ABSTRACT This article takes a closer look at the Boccaccio story upon which Paul Heyse based his famous ‘Falken‐Theorie’ of the ‘Novelle’. The essay then links Boccaccio to a general account of storytelling as an aid to survival amid the hostility of nature and human circumstances.

Vortex streets in a cavity with higher-order standing waves [PDF]
, 1997 Recently a laser analog of vortex generation behind an obstacle in a flow was demonstrated. Vortex generation occurs when tilted waves of different transverse structures are simultaneously excited in a laser. We have generalized this phenomenon to higher-

An Experimental Investigation of Flame Spreading from Bluff Body Flameholders [PDF]
, 1958 Flame spreading from 1/16 to l inch circular cylinder flame holders in two-dimensional flow was studied experimentally. Combustion wake widths were determined by use of spark Schlieren photographs at distances up to 36 inches downstream of the flame ...

Modelling Pollutant Dispersion in Urban Canyons to Enhance Air Quality and Urban Planning
Applied SciencesAir pollution in urban street canyons presents a serious health risk, especially in densely populated areas. While previous research has explored airflow characteristics in these canyons, it often lacks detailed data on pollutant dispersion and the ...

Vortex streets in walking parametric wave mixing [PDF]
, 1999 The combined effects of diffraction and Poynting vector walk-off in second-harmonic generation with pump beams that contain screw phase dislocations is addressed for what is believed to be the first time. We predict the spontaneous nucleation of multiple

Formation of Periodic Vortex Streets Driven by the Lorents Force [PDF]
Quasi-2D periodic vortex streets, driven by the Lorentz force due to the interaction of a localized magnetic field with an electrolytic current, have been investigated experimentally using a shallow water tank with a movable bottom floor.
