RISExperimental Investigation on Infrared Signatures of Axisymmetric Vectoring Exhaust Nozzle With Film Cooling and Low-Emissivity Coating
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Investigations on infrared (IR) radiation suppression of axisymmetric vectoring exhaust nozzle (AVEN) are meaningful, due to the requests for maneuverability and IR stealth capability of aircrafts. In this paper, the ...
Comparative Analysis of Infrared Signatures of Turbofan Engine Exhaust System With or Without Afterburning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow fields and infrared signatures of a turbofan engine axisymmetric exhaust system with or without afterburning have been numerically investigated. The flow fields of the exhaust system have been calculated using a ...
Experimental Investigation on Leakage and Frictional Heat Generation Characteristics of Low Hysteresis Brush Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Low hysteresis brush seals are frequently used in systems operating at a high speed in environments featuring a high temperature and pressure. The high-speed rotor comes into contact with the bottom end of the bristles of ...
Performance Monitoring of a Glass Fiber-Reinforced Polymer Bar Soil Nail during Laboratory Pullout Test Using FBG Sensing Technology
Publisher: American Society of Civil Engineers
Abstract: In this paper, the stress–strain state and the effectiveness of shear resistance of a glass fiber-reinforced polymer (GFRP) bar soil nail in a pullout test was studied in laboratory using fiber Bragg grating (FBG) sensing ...
Numerical Simulations of a Strip Footing on the Soil Slope with a Buried Pipe Using the Material Point Method
Publisher: ASCE
Abstract: Given the prevalence of such scenarios worldwide, it is of the utmost importance for geotechnical practitioners to understand the behavior of a strip footing located over a pipe buried within a slope. This study focuses ...
Modeling Pipe–Soil Interaction under Lateral Movement Using Material Point Method
Publisher: ASCE
Abstract: Excessive lateral movements of buried pipes in geohazard-prone areas frequently jeopardize the structural integrity and serviceability of pipelines, as well as the safety of the surrounding geoenvironments. Based on the ...
Field Pullout Testing and Performance Evaluation of GFRP Soil Nails
Publisher: American Society of Civil Engineers
Abstract: Glass fiber–reinforced polymer (GFRP) materials provide practical solutions to corrosion and site-maneuvering problems for civil infrastructures using conventional steel bars as reinforcements. In this study, the feasibility ...
Experimental Investigation of Pullout Behavior of Fiber-Reinforced Polymer Reinforcements in Sand
Publisher: American Society of Civil Engineers
Abstract: Fiber-reinforced polymer (FRP) bars and strips are potential alternatives to conventional soil reinforcements. In this aspect, two commonly used FRP materials are glass-FRP and carbon-FRP (GFRP and CFRP). However, the ...
Deep Learning Framework for Total Stress Detection of Steel Components
Publisher: ASCE
Abstract: Accurately obtaining the stress of steel components is of great importance for the condition assessment of civil structures. Currently, methods for structure stress detection have some drawbacks such as the capability of ...
