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 ...
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 ...
Effect of Fuels with Different Distillation Temperatures on Performance and Emissions of a Diesel Engine Run at Various Injection Pressures and Timings

Density Prediction Model of Binary or Ternary Diesel Fuel Blends with Biodiesel and Ethanol for Compression-Ignition Engine Calculations
Publisher: American Society of Civil Engineers
Abstract: Density is an important indicator for evaluating diesel fuel quality that directly affects the injection timing and injection rule of the engine, and also has a significant impact on the spray broken particle size, the ...
Effects of Gasoline Octane Number on Fuel Consumption and Emissions in Two Vehicles Equipped with GDI and PFI Spark-Ignition Engine
Publisher: ASCE
Abstract: The fuel octane number affects the fuel consumption and emission characteristics of vehicles powered by spark-ignition engines. An investigation on the effects of commercial types of gasoline with different research octane ...
