RISQuantification of a Single Gas Bubble Growth in Solvent(s)–CO2–Heavy Oil Systems With Consideration of Multicomponent Diffusion Under Nonequilibrium Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mechanistic model has been developed and validated to quantify a single gas bubble growth with considering multicomponent gas diffusion in solvent(s)–CO2–heavy oil systems under nonequilibrium conditions. Experimentally, ...
Experimental and Theoretical Quantification of Nonequilibrium Phase Behavior and Physical Properties of Foamy Oil Under Reservoir Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel and pragmatic technique has been proposed to quantify the nonequilibrium phase behavior together with physical properties of foamy oil under reservoir conditions. Experimentally, constant-composition expansion (CCE) ...
Development of an Atlantic Canadian Coastal Water Level Neural Network Model
Publisher: American Meteorological Society
Abstract: Coastal water-level information is essential for coastal zone management, navigation, and oceanographic research. However, long-term water-level observations are usually only available at a limited number of locations. ...
Analysis and Improvement of Metal Transfer Behaviors in Consumable Double Electrode GMAW Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Consumable doubleelectrode gas metal arc welding (consumable DEGMAW) is the efficient improvement of DEGMAW. Due to the variety of coupled arc and metal transfer behaviors, this paper applies static force balance theory ...
Seismic Performance of Hybrid Columns of Concrete-Filled Square Steel Tube with FRP-Confined Concrete Core
Publisher: American Society of Civil Engineers
Abstract: An experimental program that investigated the seismic performance of concrete-filled square steel tube with fiber-reinforced polymer (FRP)–confined concrete core (FCCC) column (SCFC) was conducted. Fourteen SCFC specimens ...
Numerical and Experimental Study of Temperature Field for Double Electrode Gas Metal Arc Welding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the features of double electrode gas metal arc welding (DEGMAW), a new hybrid heatsource model for DEGMAW was proposed. Using this heatsource model, the temperature fields of DEGMAW with different welding parameters ...
Study of Stability of Surrounding Rock due to the Approach of Two Excavation Faces and Face Reinforcement in a Large Cross-Section Tunnel in Weak Stratum
Publisher: American Society of Civil Engineers
Abstract: When the two excavation faces of a tunnel constructed from both the entrance and exit simultaneously in soft surrounding rock approach, the excavation surface disturbance areas are superimposed, stress and deformation in ...
Long-Term Longitudinal Deformation Characteristics of Metro Lines in Soft Soil Area
Publisher: American Society of Civil Engineers
Abstract: Metro lines buried in soft soil in coastal regions will inevitably suffer long-term uneven deformation during operation. In this study, the long-term deformation characteristics of metro lines in Shanghai soft deposits are ...
Semi-Analytical Approach to Evaluate Seismic Passive Earth Pressures Considering the Effects of Soil Cohesion and a Curvilinear Failure Surface
Publisher: American Society of Civil Engineers
Abstract: The widely acknowledged Mononobe-Okabe (MO) model is not recommended for seismic passive earth pressures analysis because it yields nonconservative results when the ratio of the wall’s to the soil’s frictional angle is ...
Research on Pre-Reinforced Regions and Strength Parameters of Shallow Tunnels in Weak Strata
Publisher: American Society of Civil Engineers
Abstract: Safety coefficient and surface settlement were chosen as evaluation indictors for non-self-stabilizing weak strata and basic self-stabilizing weak strata. Fluid mechanical interaction is used to analyze the pre-reinforcement ...
