TESTING AN EMERGING PARADIGM IN MIGRATION ECOLOGY SHOWS SURPRISING DIFFERENCES IN EFFICIENCY BETWEEN FLIGHT MODES.

Testing an emerging paradigm in migration ecology shows surprising differences in efficiency between flight modes.

To maximize fitness, flying animals should maximize flight speed while minimizing energetic expenditure.Soaring speeds of large-bodied birds are determined by flight routes and tradeoffs between minimizing time and energetic costs.Large raptors migrating in eastern North America predominantly glide between thermals that provide lift or soar along s

Numerical Simulation and Experimental Investigation of Rotating Blade Centrifugal Jet in Slurry Blast Device Used for Steel Strip Descaling

Under the requirement of clean production, a new type of slurry blast device for mechanically removing Hair Care oxide scale on the surface of steel strips is presented, which can avoid the serious problems of rapid wear, low service life, and low efficiency of the traditional abrasive water jet with a nozzle.In this paper, the numerical simulation
