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.

Guide Vane Closing Schemes for Pump Turbines Based on Transient Characteristics in S shaped Region
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the transitional processes of load rejection in a pumpedstorage station, the Sshaped characteristics of the pumpturbines can result in relatively large waterhammer and pulsating pressures. These pressures and the ...
Runaway Instability of Pump Turbines in S Shaped Regions Considering Water Compressibility
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pumpturbine characteristics greatly affect the operational stability of pumpedstorage plants. In particular, the Sshaped region of the characteristic curves leads to severe instability during runaway conditions with ...
Construction of Pump Turbine Characteristics at Any Specific Speed by Domain Partitioned Transformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pumpturbine characteristics are important for designing pumpedstorage plants and indispensable for simulating hydraulic transients, but are often not available in the preliminary design stage. Therefore, constructing a set ...
Transient Pressure Analysis of a Prototype Pump Turbine: Field Tests and Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The transient behaviors of a prototype pump turbine are very important to the safe operation of a pumped-storage power plant. This is because the water hammer pressure during transient events affects the pressure surges ...
Constant-Speed Oscillation of a Pump Turbine Observed on a Pumped-Storage Model System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hydraulic characteristics of pump turbines in off-design conditions, especially the S-shaped characteristics, are crucial for the safety and stability of the unit. To explore the S-characteristics of pump turbines ...
Mechanism of Fast Transition of Pressure Pulsations in the Vaneless Space of a Model Pump-Turbine During Runaway
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The pressure pulsations in the vaneless space of pump-turbines are extremely intense and always experience rapid time variations during transient scenarios, causing structural vibrations and even more serious accidents. ...
Effect of the Speed Factor on the Amplitude of the Blade Passing Frequency in the Vaneless Space of a Pump Turbine in Turbine Mode
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An exponential expression describing the relationship between the amplitude of the blade passing frequency in the vaneless space of a pump turbine operating in the turbine mode and the speed factor is proposed based on ...
Constant-Speed Oscillation of a Pump Turbine Observed on a Pumped-Storage Model System
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The hydraulic characteristics of pump turbines in off-design conditions, especially the S-shaped characteristics, are crucial for the safety and stability of the unit. To explore the S-characteristics of pump turbines ...
Biofidelity Assessment of the WIAMan Thorax by a Comparative Study With Hybrid III, THOR, and PMHS in Frontal Sled Testing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Warrior Injury Assessment Manikin (WIAMan) anthropomorphic test device (ATD) has been originally developed to predict and prevent injuries for occupants in military vehicles, in an underbody blast environment. However, ...
