RISExperimental and Numerical Investigations Into the Blade Tip Phantom Cooling Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the gas turbines, the blade tip is difficult to be cooled down due to the complex flow and the intense heat transfer process here. Phantom cooling has been considered a kind of second-order cooling effect to help protect ...
Novel Ductile FRP System for Concrete Reinforcement: Concept and Experimental Characterization
Publisher: American Society of Civil Engineers
Abstract: This paper presents a novel design concept for fiber reinforced polymer (FRP) composites consisting of three-dimensional (3D) printed cores and FRP helical skins as a means of ensuring adequate ductility relative to the ...
Study on the Influence of Supplementary Cementitious Materials on Fast Hardening Sulfoaluminate Cement–Engineered Cementitious Composites
Publisher: American Society of Civil Engineers
Abstract: To enhance the application effect of engineered cementitious composites in rapid repair engineering, this study prepared early strength and fast hardening sulfoaluminate cement–engineered cementitious composites (S-ECC) ...
Effect of Stress Level on the Frost Resistance and Uniaxial Compressive Properties of Desert Sand Concrete
Publisher: American Society of Civil Engineers
Abstract: Rapid freeze-thaw (F-T) tests were conducted to study the frost resistance of desert sand concrete (DSC) at different stress levels (SL), desert sand replacement rate (DSRR) and the number of F-T cycles. The impact of the ...
Effects of Different Surfactant and Furan Cosolvents on the Macroscopic and Microscopic Properties of Ethanol-Diesel Fuel Blends
Publisher: American Society of Civil Engineers
Abstract: Ethanol is considered a clean, cost-effective, carbon-neutral fuel. In this study, the effect of a surfactant (Span 80/Tween 80) and cosolvent (furan) on the macroscopic and microscopic mutual solubility characteristics ...
