Abstract: Previous research has shown that as wind turbine rotor designs increase in diameter they approach flutter instabilities. Recent blade designs incorporate blade sweep to lower fatigue loads and increase rotor diameter for ...

Abstract: An unbranched perfluoropolyether is the current ball bearing lubricant for deep space flight. We report measurements of viscosity to moderate pressures for the calculation of pressure-viscosity ...

Abstract: ind rose summaries, which provide a basis for understanding and evaluating the climatological behavior of local wind, have a directional bias if a conventional method is used in their generation. Three techniques used to ...

Abstract: The Eyring sinh law is presently the most well-accepted model for shear-thinning of EHD lubricants at high pressure. It was, however, not accepted for this purpose by Eyring, who found it to ...

Abstract: The authors have produced a compelling argument to explain EHL dimple formation as resulting from a temperature-viscosity effect. I believe that their explanation is correct. They have solved ...

Abstract: Congratulations to the four ASCE Student Member, who won the zone essay competitions for the 2001 Daniel W. Mead Prize for the Younger Members. Three of the winning essays appear in this issue. The other essay, the overall ...

Abstract: Recent advances in high pressure rheometry have elucidated the shear response of liquid lubricants at the high shear stress characteristic of the traction generating region of lubricated concentrated ...
