RISBehaviors of a Hole-Pattern Seal With Wet-Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hole-pattern (HP) seals are widely used in centrifugal compressors to control leakage. This paper investigates the behaviors of an HP with wet-gas mixtures. The mixture consists of oil and air with inlet liquid volume ...
Effects of Increased Tooth Clearance on the Performance of a Labyrinth Seal With Oil-Rich Bubbly Laminar Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, multiphase pumps have become more and more popular because of the capability to simplify the process, reduce the footprint, and lower the cost. To compensate for the axial thrust force, an annular seal is ...
A Study for Rotordynamic and Leakage Characteristics of a Long-Honeycomb Seal With Two-Phase, Mainly Air Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the impact of the oil (silicone oil PSF-5cSt) presence in the air on the leakage and rotordynamic characteristics of a long-honeycomb seal with length-to-diameter ratio L/D = 0.748 and diameter ...
Experimental Study on the Performance of a See-Through Labyrinth Seal With Two-Phase, Mainly-Liquid Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With the increasing demand of the oil and gas industry, many pump companies are developing multiphase pumps, which can handle liquid–gas flow directly without separating the liquid from a mixed flow. The see-through labyrinth ...
Multiple-Fault Classification for Hot-Mix Asphalt Production by Machine Learning
Publisher: American Society of Civil Engineers
Abstract: To monitor the condition of the hot-mix asphalt production process, the quality and consistency of input aggregates are widely used for monitoring process variation. Current practice involves taking samples from actual ...
Deep Atlantic Ocean Warming Facilitated by the Deep Western Boundary Current and Equatorial Kelvin Waves
Publisher: American Meteorological Society
Abstract: AbstractIncreased heat storage in deep oceans has been proposed to account for the slowdown of global surface warming since the end of the twentieth century. How the imbalanced heat at the surface has been redistributed ...
Preswirl and Mixed-Flow (Mainly Liquid) Effects on Rotordynamic Performance of a Long (L/D = 0.75) Smooth Seal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Measured results are presented for rotordynamic coefficients and mass leakage rates of a long smooth annular seal (length-to-diameter ratio L/D = 0.75, diameter D = 114.686 mm, and radial clearance Cr = 0.200 mm) tested ...
Integrated Design of Axial Slot Casing Treatment and Blades in a Low-Speed Single Stage Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Casing treatment has been used to enhance the stability of axial-flow compressor by extending the stall margin; it also induces strong interaction with compressor blades, as demonstrated in the open literature. Revealing ...
Fully Nonlinear Interaction of Water Waves and a Submerged Cylinder With Wave Breaking Detection and Suppression
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the nonlinear interaction of regular water waves propagating over a fixed and submerged circular cylinder is numerically studied. At the structure’s lee side, the free surface profile experiences strong ...
Aerodynamic Optimization of a Winglet-Shroud Tip Geometry for a Linear Turbine Cascade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a continued study on a previously investigated novel winglet-shroud (WS) (or partial shroud) geometry for a linear turbine cascade. Various widths of double-side winglets (DSW) and different locations ...
