RISAerodynamic Interaction Between an Incoming Vortex and Tip Leakage Flow in a Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In turbines, secondary vortices and tip leakage vortices form in the blade passage and interact with each other. In order to understand the flow physics of this vortices interaction, the effects of incoming vortex on the ...
Aerodynamic Effects of an Incoming Vortex on Turbines With Different Tip Geometries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental and numerical methods were used to investigate the aerodynamic effects of a near-casing streamwise incoming vortex flow on the tip leakage flow of different tip geometries in an unshrouded high-pressure turbine. ...
Convolutional Dimension-Reduction With Knowledge Reasoning for Reliability Approximations of Structures Under High-Dimensional Spatial Uncertainties
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Along with the rapid advancement of additive manufacturing technology, 3D-printed structures and materials have been successfully employed in various applications. Computer simulations of these structures and materials are ...
Retired Lithium-Ion Battery Pack Disassembly Line Balancing Based on Precedence Graph Using a Hybrid Genetic-Firework Algorithm for Remanufacturing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electric vehicle production is subjected to high manufacturing cost and environmental impact. Disassembling and remanufacturing the lithium-ion power packs can highly promote electric vehicle market penetration by procuring ...
Lessons Learned Toward Estimating the High-Pressure Turbine Inlet Temperature Profile Using Measurements Acquired at the High-Pressure Turbine Exit
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To achieve higher thermal efficiency, gas turbines operate at increasingly higher turbine inlet temperatures, leading to the need for advanced cooling methods such as film cooling, impingement cooling, and passage cooling ...
Influence of the Planetary Movement of Tool on the Aspect Ratio of Micro Holes Machined by Micro-Ultrasonic Machining
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The micro-ultrasonic machining (USM) is suitable for machining hard and brittle materials. When a micro hole is drilled deeply using micro-USM, machining speed slows down and the breakage of micro tool may occur. To solve ...
Lightweight Alkali-Activated Material from Mining and Glass Waste by Chemical and Physical Foaming
Publisher: American Society of Civil Engineers
Abstract: A foamed alkali-activated material (FAAM) based on tungsten mining waste (TMW) and municipal waste glass (WG) is fabricated by using aluminum powder and organic surfactant foaming agents. The compressive strength and density ...
Modeling Lane-Choice Behavior to Optimize Pricing Strategy for HOT Lanes: A Support Vector Regression Approach
Publisher: American Society of Civil Engineers
Abstract: High-occupancy toll (HOT) lanes can better utilize road resources by allowing low-occupancy vehicle (LOV) drivers to pay a toll and use high-occupancy vehicle (HOV) lanes. In such a system, the toll price plays a key role ...
