RISEffect of Temperature on Simulated Flow-Induced Vibration Wear Behavior of Inconel 690 Alloy Mated With 304 SS in Pressurized Steam/Water Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Steam generator tube, which is commonly made of Inconel 690 alloy, is suffered from flow-induced vibration and worked under high-temperature and high-pressure water/steam environment. This working condition leads to ...
Effect of Viscoelasticity on Arterial-Like Pulsatile Flow Dynamics and Energy
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Time-dependent arterial wall property is an important but difficult topic in vascular mechanics. Hysteresis, which appears during the measurement of arterial pressure–diameter relationship through a cardiac cycle, has been ...
Study of Buffeting Excitation Acting on Coil Tube Bundles in Cross Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The amplitudes induced by random excitation forces on the tubes bring continuous friction between the tube and supports, which results in gradual failure of the tubes due to fretting wear. Therefore, it is very important ...
Calculations of the Stratospheric Quasi-Biennial Oscillation for Time-Varying Wave Forcing
Publisher: American Meteorological Society
Abstract: One-dimensional calculations are carried out for the time evolution of the equatorial lower stratospheric mean zonal wind forced by time-varying equatorial Kelvin and mixed Rossby?gravity waves. If the time variation of ...
Fluid Excitation Forces on a Tightly Packed Tube Bundle Subjected in Cross-Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluid excitation forces acting on stationary cylinders with cross-flow are the coupling of vortex shedding and turbulence buffeting. Those forces are significant in the analytical framework of fluid-induced vibration in ...
Different Responses of Sea Surface Temperature in the South China Sea to Various El Niño Events during Boreal Autumn
Publisher: American Meteorological Society
Abstract: his study investigates variations of sea surface temperature (SST) anomalies in the South China Sea (SCS) during developing autumn of various El Niño events. The warm SST anomalies are observed in the SCS for canonical El ...
Experiment Study on Fluidelastic Instability of Tube Bundles Consisting of Different Frequency Tubes With Visual Image Processing System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluidelastic instability (FEI) is the most harmful vibration mechanism for heat exchangers. Due to the inevitable manufacturing precision and assembly error, natural frequencies of tubes are not equal in the ideal condition. ...
Experiment on the Excitation of Vapor Behavior and the Vibration by Thermal Flow Under C-Tube Pool Boiling Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As an important safety equipment in nuclear system, the passive residual heat removal heat exchanger (PRHR HX) with C-tube is responsible for timely removing heat from the reactor core in accident. A C-tube heating device ...
Effect of Vessel Tortuosity on Stress Concentration at the Distal Stent–Vessel Interface: Possible Link With New Entry Formation Through Biomechanical Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational approach is used to investigate potential risk factors for distal stent graft-induced new entry (dSINE) in aortic dissection (AD) patients. Patient-specific simulations were performed based on computed ...
