RISErosive-Corrosive Wear of Copper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Copper specimens whose temperature was varied from room temperature to 500°C were eroded by sand particles. The amount of metal removed increased monotonically over this temperature range ...
Formation of Soot in Ethylene–Air Partially Premixed Flames Over a Wide Range of Premixedness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports an investigation of soot formation in ethylene–air partially premixed flames (PPFs) over a wide range of premixedness. An axisymmetric co-flow configuration is chosen to establish PPFs from the fully ...
Experimental Characterization and Control of Miniaturized Pneumatic Artificial Muscle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Robotic surgical tools used in minimally invasive surgeries (MIS) require miniaturized and reliable actuators for precise positioning and control of the endeffector. Miniature pneumatic artificial muscles (MPAMs) are a ...
A Wall-Distance-Free k-ε Model With Enhanced Near-Wall Treatment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper evaluates a wall-distance-free low-Re k-ε turbulence closure model which incorporates an extra source term in the ε transport equation designed to increase the level of ε in ...
Experimental Investigation of Cavity-Induced Acoustic Oscillations in Confined Supersonic Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The focus of the present work is the acoustic oscillations exhibited by confined supersonic flow past a rectangular cavity of varying length-to-depth (L∕D) ratio, with a view to identify optimal ...
Analysis and Design Approach for Large Storage Caverns
Publisher: American Society of Civil Engineers
Abstract: This paper presents a case study of an underground crude oil storage project. This storage site is researched with detailed field and laboratory investigations. The layout, cross section, and elevation of the caverns are ...
Potential Computational Benefits of Geometric, Kinematic, and Behavioral Downsampling of Microscopic Traffic Network Simulation
Publisher: American Society of Civil Engineers
Abstract: This paper introduces the concept of microscopic simulation system scalability for the purpose of reducing the computational requirements of microsimulation modeling of large-scale traffic networks. This exploratory stage ...
Effect of Outlet Boundary Condition on the Acoustic Modeshape and Flame Dynamics of a Partially Premixed Swirl Stabilized Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Industrial gas turbines commonly use lean premixed swirl stabilized combustors that are prone to thermo-acoustic instabilities. Combustor testing involves several steps ranging from atmospheric to high-pressure conditions. ...
The Effect of Multiple Coexisting Convective Modes in Determining Thermoacoustic Behavior of a Partially Premixed Swirl Flame
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study focuses on the effect of multiple heat release mode interactions on the amplitude of unsteady pressure oscillation for a partially premixed radial swirl burner, which uses methane as fuel. A range of operating ...
Computational Study of Resonance Suppression of Open Sunroofs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A 2-D computational study of flow over a fully open sunroof of a car with a passenger compartment has been done on a scalar workstation. The critical velocity for resonance in the passenger ...
