RISInfluence of Hydro-Mechanical Coupling on Tunnel Response in Clays
Publisher: American Society of Civil Engineers
Abstract: The design of deep tunnels underneath the water-table in clayey soils should carefully take into account the influence of pore pressures and seepage forces on the stability of the excavation and on the loading conditions ...
Influence of Endwall Flow on Airfoil Suction Surface Midheight Boundary Layer Development in a Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the results of an analysis to assess the influence of cascade passage endwall flow on the airfoil suction surface midheight boundary layer development in a turbine cascade. ...
Characterization and DEM Modeling of Shear Zones at a Large Dam Foundation
Publisher: American Society of Civil Engineers
Abstract: Cataclastic rocks and fault gouge present highly variable properties, from those of soil-like materials to those of competent rock mass. In most cases, the entire rock mass, or internal major shear zones, can be represented ...
Visco-Elasto-Plastic Characterization in the Small Strain Domain of Cement Bitumen–Treated Materials Produced at Low Temperatures
Publisher: ASCE
Abstract: In the framework of recycling techniques employed in maintenance and rehabilitation projects for the road industry, cement bitumen–treated materials (CBTMs) provide good performance as well as economic and environmental ...
Electrochemical Measurements for Real-Time Stochastic Reconstruction of Large-Scale Dynamics of a Separated Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ability of electrochemical sensors to properly measure wall shear stress is here considered for using these sensors as potential candidates for time-resolved estimation of the large-scale activity occurring in the flow ...
Heat Transfer in Rotating Serpentine Passages With Trips Normal to the Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments were conducted to determine the effects of buoyancy and Coriolis forces on heat transfer in turbine blade internal coolant passages. The experiments were conducted with a large-scale, ...
An Experimental Study of Endwall and Airfoil Surface Heat Transfer in a Large Scale Turbine Blade Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Local rates of heat transfer on the endwall, suction, and pressure surfaces of a large scale turbine blade cascade were measured for two inlet boundary layer thicknesses and for a Reynolds ...
Effect of RAP Source on Compactability and Behavior of Cold-Recycled Mixtures in the Small Strain Domain
Publisher: ASCE
Abstract: Cold recycled materials (CRMs) are products of modern recycling techniques that are used in maintenance and rehabilitation of pavement structures with significant economical and environmental benefits. CRM mixes are produced ...
Modeling of a Fractional Order Element Based on Bacterial Cellulose and Ionic Liquids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a novel fractional-order element (FOE) is modeled in a wide frequency range. The FOE is based on a green biopolymer, i.e., bacterial cellulose (BC), infused with ionic liquids (ILs). The modeling is performed ...
Effect of Sea Breeze on Air Pollution in the Greater Athens Area. Part I: Numerical Simulations and Field Observations
Publisher: American Meteorological Society
Abstract: Numerical simulations compared with field measurements are used to explain the effect of sea breezes on photochemical smog episodes in Athens during the Mediterranean Campaign of Photochemical Tracers on 12?14 September ...
