Experiments in Aerodynamics 1

Aerodynamics in Cardiac CT.

I t seems not long ago that invasive coronary angiography was considered as the undisputed diagnostic standard and management determining test for patients with ischemic heart disease. Registry data have shown that reliance on noninvasive testing for myocardial ischemia, positioned as a gatekeeper to restrict referral to the catheterization laboratory, is far from optimal in clinical practice. ...

Surprises in cycling aerodynamics

Federal Lab. for Materials Testing and Research (Empa) Dübendorf Switzerland l 5 Bakala Academy Athletic Performance Center Univ. of Leuven Heverlee, Belgium Surprises in cycling aerodynamics T he greatest potential for improvement in cycling speed is aerodynamic” [1]. At racing speeds (about 54 km/h or 15 m/s in time trails), the aerodynamic resistance or drag is about 90% of the total resista...

Forward flight of birds revisited. Part 1: aerodynamics and performance

This paper is the first part of the two-part exposition, addressing performance and dynamic stability of birds. The aerodynamic model underlying the entire study is presented in this part. It exploits the simplicity of the lifting line approximation to furnish the forces and moments acting on a single wing in closed analytical forms. The accuracy of the model is corroborated by comparison with ...

Aerodynamics of [ r ] in tonogenesis

Explanation and discovery in aerodynamics

The purpose of this paper is to discuss and clarify the explanations commonly cited for the aerodynamic lift generated by a wing, and to then analyse, as a case study of engineering discovery, the aerodynamic revolutions which have taken place within Formula 1 in the past 40 years. The paper begins with an introduction that provides a succinct summary of the mathematics of fluid mechanics.
