ASME ( American Society of Mechanical Engineers )
Description: The American Society of Mechanical Engineers (ASME) is a professional association that, in its own words, "promotes the art, science, and practice of multidisciplinary engineering and allied sciences around the globe" via "continuing education, training and professional development, codes and standards, research, conferences and publications, government relations, and other forms of outreach." ASME is thus an engineering society, a standards organization, a research and development organization, a lobbying organization, a provider of training and education, and a nonprofit organization. Founded as an engineering society focused on mechanical engineering in North America, ASME is today multidisciplinary and global.

Analysis of Tilting Effects and Geometric Nonuniformities in Micro-hydrostatic Gas Thrust Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Massachusetts Institute of Technology (MIT) microengine rotors are supported by hydrostatic gas journal and hydrostatic gas thrust bearings. Due to the low length-to-diameter ratio of the ...
Modeling and Experimental Investigation of Micro-hydrostatic Gas Thrust Bearings for Micro-turbomachines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One major challenge for the successful operation of high-power-density micro-devices lies in the stable operation of the bearings supporting the high-speed rotating turbomachinery. Previous modeling ...
A Criterion for Axial Compressor Hub-Corner Stall
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new criterion for estimating the onset of three-dimensional hub-corner stall in axial compressor rotors and shrouded stators. A simple first-of-a-kind description of hub-corner ...
A Novel Turbomachinery Air-Brake Concept for Quiet Aircraft
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel air-brake concept for next-generation, low-noise civil aircraft is introduced. Deployment of such devices in clean airframe configuration can potentially reduce aircraft source noise and ...
Unsteady Flow and Dynamic Behavior of Ultrashort Lomakin Gas Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultrashort microscale high-speed gas bearings exhibit a whirl instability limit and dynamic behavior much different from conventional hydrostatic gas bearings. In particular, the design space for ...
Erratum: “Scaling Laws for Ultra-Short Hydrostatic Gas Journal Bearings” [Journal of Vibration and Acoustics, 2005, 127(3), pp. 254–261]
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The exponents of the clearance to radius term (C∕R) in the scaling law for damping ratio ζ in Eqs. 19,20 were inadvertently switched between these two equations. Equations 19,20 should ...
Hydrostatic Gas Journal Bearings for Micro-Turbomachinery
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Several years ago an effort was undertaken at MIT to develop high-speed rotating MEMS (Micro Electro-Mechanical Systems) using computer chip fabrication technology. To enable high-power density ...
Rotating Stall Control in a High-Speed Stage With Inlet Distortion: Part II—Circumferential Distortion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the first attempt to stabilize rotating stall in a single-stage transonic axial flow compressor with inlet distortion using active feedback control. The experiments were ...
Scaling Laws for Ultra-Short Hydrostatic Gas Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The journal bearings of the MIT micro-devices are located at the outer periphery of the rotor and are designed to operate at rotational speeds of order two million rpm in order to enable ...
Rotating Stall Control in a High-Speed Stage With Inlet Distortion: Part I—Radial Distortion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the first attempt to stabilize rotating stall in a single-stage transonic axial flow compressor with inlet distortion using active feedback control. The experiments were ...
