RISInfluence of Specimen Preparation on the Liquefaction Behaviors of Sand and Its Mesoscopic Explanation
Publisher: ASCE
Abstract: Specimen preparation methods and the resulting fabric can significantly influence the mechanical behavior of sand. To clarify the influence of specimen preparation methods on liquefaction behavior, a series of undrained ...
Effects of Reynolds Number and Freestream Turbulence Intensity on the Unsteady Boundary Layer Development on an Ultra-High-Lift Low Pressure Turbine Airfoil
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of Reynolds numbers and the freestream turbulence intensities (FSTIs) on the unsteady boundary layer development on an ultra-high-lift low-pressure turbine airfoil, so-called T106C, are ...
Combined Effects of Surface Trips and Unsteady Wakes on the Boundary Layer Development of an Ultra-High-Lift LP Turbine Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental investigation of the combined effects of upstream unsteady wakes and surface trips on the boundary layer development on an ultra-high-lift low-pressure turbine blade, known as ...
Influence of River Sinuosity on the Distribution of Conservative Pollutants
Publisher: American Society of Civil Engineers
Abstract: The influence of river sinuosity on the distribution characteristics of pollutants in a wide river is investigated three-dimensionally with a numerical model. It is found that, for a meandering river, the hydrodynamic force ...
Investigation of Suction Effects Due to Stress Release with Compacted MX80 Bentonite
Publisher: ASCE
Abstract: In this study, the suction induced by stress release was investigated by measuring the suction of instantaneously unloaded MX80 bentonite specimens after wetting in an oedometer either under different vertical stresses or ...
Numerical Simulations of the Prethawing Performance of Lime-Energy-Column Embankments in Warm Permafrost Regions
Publisher: American Society of Civil Engineers
Abstract: The thawing settlement of highway embankments remains an engineering challenges in permafrost regions. Lime-energy-columns (LECs) have the potential to constrain the total amount of such settlement by prethawing the warm ...
Separation and Transition Control on an Aft-Loaded Ultra-High-Lift LP Turbine Blade at Low Reynolds Numbers: High-Speed Validation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the second part of an investigation of the combined effects of unsteadiness and surface roughness on an aft-loaded ultra-high-lift low-pressure turbine (LPT) profile at low ...
Separation and Transition Control on an Aft-Loaded Ultra-High-Lift LP Turbine Blade at Low Reynolds Numbers: Low-Speed Investigation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study was conducted to improve the performance of an aft-loaded ultra-high-lift low-pressure turbine blade known as U2 at low Reynolds numbers. This was achieved by manipulation ...
Thaw Settlement and Mechanical Properties of Admixture-Stabilized Frozen Soil
Publisher: ASCE
Abstract: Roads and other infrastructure in Western Alaska are difficult to design and build owing to the high cost of construction materials and the ice-rich permafrost foundation. The present study explores methods to treat locally ...
Liquefaction-Induced Buckling Failure of Group-Pile Foundation and Countermeasure by Partial Ground Improvement
Publisher: American Society of Civil Engineers
Abstract: Pile foundations may lose their lateral resistance in earthquake-induced liquefaction and may fail not only by bending and shear forces but also buckling. Although research has been done on the buckling of pile foundations, ...
