RISOptimization of Temperature Field by Differentiating Number of Circumferential Control Zones in Local Post Weld Heat Treatment on 9%Cr Heat-Resistant Steel Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports the optimal use of control zones to achieve required uniformity of temperature distribution in local postweld heat treatment of welds in 9% Cr heat-resistant large pipe system. In this research, local ...
Strength Analysis of Syntactic Foams Using a Three Dimensional Continuum Damage Finite Element Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The failure behavior of the syntactic foams is investigated based on a threedimensional (3D) micromechanical finite element (FE) model, by varying the volume fraction, the wall thickness of the hollow particles, and the ...
Test Model of a Long-Span Arch-Shaped Steel Tower Cable-Stayed Bridge
Publisher: American Society of Civil Engineers
Abstract: The Zhijiang River Bridge was used as a test model to study the mechanical behavior of long-span arch-shaped steel tower cable-stayed bridge. The test model was designed and simulated with a finite element method, which ...
Experimental Study on Gas–Liquid Performance and Prediction of Shaft Power and Efficiency by Dimensionless Coefficients in a Multistage Electrical Submersible Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electrical submersible pumps (ESPs) widely used in oil-gas artificial lift consume a lot of electric energy in long-term operation. This paper mainly focuses on the gas–liquid performance and predicting shaft power and ...
Interstage Performance and Power Consumption of a Multistage Mixed-Flow Electrical Submersible Pump in Gas–Liquid Conditions: An Experimental Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance degradation of electrical submersible pump (ESP) caused by high gas volume fraction (GVF) has always been a common problem in the field of oil and gas production. Experiments are conducted to investigate ...
Experimental Study of Gas–Liquid Pressurization Performance and Critical Gas Volume Fractions of a Multiphase Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas entrainment may cause pressurization deterioration and even failure of pumps under conditions of high inlet gas volume fraction (GVF). When the inlet GVF increases to a critical value, an obvious deterioration performance ...
An Enhanced Adaptive Chirp Mode Decomposition for Instantaneous Frequency Identification of Time-Varying Structures
Publisher: ASCE
Abstract: Adaptive chirp mode decomposition (ACMD) is a novel decomposition algorithm, which can decompose the multicomponent signals and identify its instantaneous frequencies (IFs) simultaneously. It is crucial for ACMD to predefine ...
