RISNumerical Study of Double-Jet Film Cooling on a Semi-Cylindrical Leading Edge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical investigation is performed for double-jet film cooling (DJFC) on a semi-cylindrical leading edge under four momentum flux ratios. Three rows of film cooling holes are distributed on the leading edge, wherein ...
Potential and Viscous Interactions for a Multi-Blade-Row Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computationally efficient time-accurate vortex method for unsteady incompressible flows through multiple blade row systems is presented. The method represents the boundary surfaces using vortex ...

Effects of Temperature Variations on the In-Plane Stability of Steel Arch Bridges
Publisher: American Society of Civil Engineers
Abstract: The in-plane stability of shallow parabolic arches subjected to a central concentrated load and temperature variations was investigated in this paper. The virtual work principle method was used to establish the non-linear ...
Short-Term Flexural Behavior of Prestressed Glulam Beams Reinforced with Curved Tendons
Publisher: ASCE
Abstract: The short-term flexural behavior of prestressed glulam beams reinforced with curved tendons was investigated via four-point bending of 12 glulam beams. These beams were equally divided into four groups of three identical ...
Influence of Silica Fume and Additives on Unconfined Compressive Strength of Cement-Stabilized Marine Soft Clay
Publisher: ASCE
Abstract: This study presents results on the influence of silica fume (SF) and additives on the unconfined compressive strength (UCS) of ordinary portland cement (OPC)-stabilized salt-rich marine soft clay. The effects of additives ...
Hierarchical Modeling Method for DEM Simulation and Its Application in Soil–Pile–Cap Interaction and Impact Case
Publisher: American Society of Civil Engineers
Abstract: By developing a hierarchical modeling method, using discrete element analysis software PFC3D, a discrete-element method (DEM) model can be built and solved more efficiently. In this method, smaller particles are used for ...
Interactions between Building Integrated Photovoltaics and Microclimate in Urban Environments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: BIPV (building integrated photovoltaics) has progressed in the past years and become an element to be considered in city planning. BIPV has significant influence on microclimate in urban ...
Numerical Analysis of the Effect of Misaligned Guide Vanes on Improving S-Shaped Characteristics for a Pump-Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The S-shaped characteristic curves in pump-turbines complicate synchronization with the electrical grid and affect system safety. Misaligned guide vanes (MGVs) are one of the most effective solutions to avoid S-shaped ...
Chloride Diffusion Prediction in Concrete through Mathematical Models Based on Time–Dependent Diffusion Coefficient and Surface Chloride Concentration
Publisher: ASCE
Abstract: This paper compared several mathematical models predicting chloride penetration in concrete by employing a time-dependent diffusion coefficient for a number of analytical solutions of Fick’s second law. We propose calibrated ...
