RISCarbon Footprint of Seawater Desalination Technologies: A Review
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As an important and effective way of mitigating water shortages, desalination has steadily and rapidly increased its global capacity over the decades. This raises concern about its environmental impacts, especially its ...
The Role of Typhoon Songda (2004) in Producing Distantly Located Heavy Rainfall in Japan
Publisher: American Meteorological Society
Abstract: When Typhoon Songda (2004) was located southeast of Okinawa over the western North Pacific during 2?4 September 2004, a heavy rainfall event occurred over southern central Japan and its adjacent seas, more than 1200 km ...
Effect of Slick Water on Permeability of Shale Gas Reservoirs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, we analyzed the flow-back resistance of slick water fracturing fluid in shale reservoirs. The flow-back resistance mainly includes capillary force, Van der Waals (VDW) force, hydrogen bond force, and hydration ...
Metallurgical Investigation and Failure Analysis in GTD-111 Stage 2 Buckets From an Industrial F-Class Gas Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A utility experienced cracking in multiple stage 2 buckets (S2Bs) in a large F-class power generation gas turbine after only 7348 h and 31 starts following a standard repair and rejuvenation heat treatment cycle. The blades ...
Exergetic Efficiency of Reverse Osmosis Desalination Systems: Definitions and Discussions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reverse osmosis (RO) desalination is the dominant desalination technology worldwide. The exergetic efficiency—which is recognized as a true measure from a thermodynamic viewpoint—of RO systems has been addressed by many ...
Synoptic Control of Convective Rainfall Rates and Cloud-to-Ground Lightning Frequencies in Warm-Season Mesoscale Convective Systems over North China
Publisher: American Meteorological Society
Abstract: AbstractThis study examines whether environmental conditions can control convective rainfall rates and cloud-to-ground (CG) lightning frequencies in mesoscale convective systems (MCSs) over north China (NC). A total of 60 ...
Effect of Indirect Cryogenic Cooling on the Machining Accuracy and
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cutting deformation and cracks are common problems during the machining of
Force-Induced Deformation Mechanism for Cylindrical Shell Thin-Walled Parts Milling With Ice Supporting: Modeling and Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Improving the rigidity of the process system in the cutting region of thin-walled parts is a challenging problem to ensure machining accuracy. For limited structural space, the use of ice support is an effective method. ...
Cable Force Distribution and Motion Control for a Cable-Driven Super-Redundant Robot Under Stiffness Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cable-driven super-redundant robots (CDSSR) with slender and flexible bodies have wide application potential in narrow spaces. However, the control accuracy of the robot is affected by the instability of the operating ...
Development of an In-Pipe Robot With Differential Screw Angles for Curved Pipes and Vertical Straight Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The in-pipe robots based on screw drive mechanism are very promising in the aspects of pipe inspecting and maintaining. The novel design of an in-pipe robot with differential screw angles is presented for the curved pipes ...
