RISThruster and Hull Interaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A hybrid method which couples a vortexlattice method (VLM) solver and a ReynoldsAveraged Navier–Stokes (RANS) solver is applied to simulate the interaction between a dynamic positioning (DP) thruster and a floating ...
Structural Stiffness and Damping Coefficients of a Multileaf Foil Bearing With Bump Foils Underneath
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a multileaf foil bearing (MLFB), which consists of four resilient top foils and four stiff bump foils underneath; thus, a high supporting capacity and a high damping capacity can be achieved. A specially ...
Particle Image Velocimetry Experiment and Computational Fluid Dynamics Simulation of Flow Around Rigid Cylinder
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work focuses on the study of the flow around a rigid cylinder with both particle image velocimetry (PIV) experiment and computational fluid dynamics (CFD) simulation. PIV measurements of the flow field downstream of ...
Uncertainty in Future High Flows in Qiantang River Basin, China
Publisher: American Meteorological Society
Abstract: ncertainties in high flows originating from greenhouse gas emissions scenarios, hydrological model structures, and their parameters for the Jinhua River basin, China, were assessed. The baseline (1961?90) and future (2011?40) ...
Interfacial Compounds Characteristic and Its Reliability Effects on SAC305 Microjoints in Flip Chip Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study mainly focuses on site effects of the Ni pad interface on intermetallic compounds (IMCs) characteristic during assembly reflowing, and attempts to provide a reasonable explanation for this particular finding. ...
Comparative Performance Assessment of a U-Shaped Recuperative Radiant Tube under Conventional and MILD Combustion Modes
Publisher: American Society of Civil Engineers
Abstract: Moderate and intense low-oxygen dilution (MILD) combustion, characterized by low reaction rate, uniform heat flux, and significantly reduced pollutants, is a promising technology which is widely used in various industries. ...
Effect of Wake Alignment on Turbine Blade Loading Distribution and Power Coefficient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes the use of a lifting line model in order to determine the optimum loading on a marine turbine's blades. The influence of the wake and its geometry is represented though the use of a full wake alignment ...
Creep Failure Behavior of Notched Structure in the Simulated Steam Turbine Rotor: Experimental and Damage Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Notched structures widely exist in steam turbine components in fossil power plant, e.g., the groove of the rotor, etc. Previous studies indicate that creep failures occur at the groove of the rotor or the adjacent regions. ...
Assessment on Strain-Based and Stress-Based Design Strategies for Components at Elevated Temperatures: A Comparative Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Geometrical discontinuities (such as holes and grooves) widely exist in many components, which operate at elevated temperatures. Creep assessment of the geometrical discontinuities is essential for the safe operation of ...
