2. Aerodynamic Simulation This paper reviews some of the progress in computational aerodynamics over the last decade and describes what remains to be done in the years ahead. The discussion includes a description of the Numerical Aerodynamic Simulation Program objectives, computational goals, and implementation plans.

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. ...

Race car performance depends on elements such as the engine, tires, suspension, road, aerodynamics, and of course the driver. In recent years, however, vehicle aerodynamics gained increased attention, mainly due to the utilization of the negative lift (downforce) principle, yielding several important performance improvements. This review briefly explains the significance of the aerodynamic down...

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...
