RISA Review of Droplet Dynamics and Vaporization Modeling for Engineering Calculations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present paper reviews the methodologies for representing the droplet motion and vaporization history in two-phase flow computations. The focus is on the use of droplet models that are ...
An Elastic Adhesion Model for Contacting Cylinder and Perfectly Wetted Plane in the Presence of Meniscus
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present research concerns the elastic contacting adhesion of a cylinder with a perfectly wetted plane in the presence of a meniscus. The Laplace pressure due to the meniscus is simplified ...
Experimental Investigation of Capillary-Induced Rewetting in a Flat Porous Wicking Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental program was conducted to investigate the rewetting characteristics of liquid flowing through multiple layers of screen mesh covering a heated vertical plate. Data obtained for ...
Fully Nonstationary Analytical Earthquake Ground-Motion Model
Publisher: American Society of Civil Engineers
Abstract: A versatile, nonstationary stochastic ground-motion model accounting for the time variation of both intensity and frequency content typical of real earthquake ground motions is formulated and validated. An extension of the ...
Closed-Form Solutions for the Response of Linear Systems to Fully Nonstationary Earthquake Excitation
Publisher: American Society of Civil Engineers
Abstract: New explicit closed-form solutions are derived for the evolutionary correlation and power spectral–density (PSD) matrices characterizing the nonstationary response of linear elastic, both classically and nonclassically ...
An Adhesion Model for Elastic-Contacting Fractal Surfaces in the Presence of Meniscus
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The strong stiction of adjacent surfaces with meniscus is a major design concern in the devices with a microsized interface. The present research concerns the elastic adhesion of rough fractal ...
Effect of Branch Orientation on Annular Two-Phase Flow in T-Junctions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental data on dividing steam-water two-phase annular flow in T-junctions with horizontal inlet and downwardly inclined branches were obtained. The experiments were performed under experimental ...
Thermal Treatment of Waste Activated Sludge Using Liquid Boiling
Publisher: American Society of Civil Engineers
Abstract: In this work we investigated the use of a short time, low superheat boiling process to treat biological sludge. The treated sludge would exhibit a deteriorated filterability, and a marked increase in soluble organics ...
Discharging Compacted Sediment by Underwater Blasting in Conjunction with a Desilting Tunnel in the Tseng-Wen Reservoir of Taiwan
Publisher: ASCE
Abstract: Sediments transported by heavy rainfall result from frequent typhoons in the Tseng-Wen reservoir, which now comprise one-third of the capacity of the reservoir. Yearly increases of 6.56 million m3 deposits are planned for ...
Treating High-Turbidity Water Using Full-Scale Floc Blanket Clarifiers
Publisher: American Society of Civil Engineers
Abstract: Dynamic responses of the blanket in full-scale flat-bottom type floc blanket clarifiers at the PingTsan Water Works, Taiwan Water Supply Corporation, were monitored given a step-change in coagulant (polyaluminum chloride, ...
