RISSimulating Heat Transfer Through Periodic Structures With Different Wall Temperatures: A Temperature Decomposition Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To simulate heat transfer processes through periodic devices with nonuniform wall temperature distributions, we propose to decompose the regular temperature into two parts: namely the transient part and the equilibrium ...
Simple Method for Prediction of the Soil Collapse Behavior due to Wetting
Publisher: American Society of Civil Engineers
Abstract: It is widely accepted that the results of wetting tests conducted on collapsible soils by reducing matric suction in consecutive steps in the laboratory provide reliable experimental data for interpreting the soil collapse ...
The Formation of Parasitic Capillary Ripples on Gravity–Capillary Waves and the Underlying Vortical Structures
Publisher: American Meteorological Society
Abstract: The evolution of moderately short, steep two-dimensional gravity?capillary waves, from the onset of the parasitic capillary ripples to a fully developed quasi-steady stage, is studied numerically using a spectrally accurate ...
Enhanced Energy Dissipation by Parasitic Capillaries on Short Gravity–Capillary Waves
Publisher: American Meteorological Society
Abstract: The increased energy dissipation caused by the formation of parasitic capillary wavelets on moderately short, steep gravity?capillary waves is studied numerically. This study focuses on understanding the mechanism leading ...
Thermoeconomic Analysis of a Combined Natural Gas Cogeneration System With a Supercritical CO2 Brayton Cycle and an Organic Rankine Cycle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a new type of Gas Turbine Cycle-supercritical CO2 Brayton/organic Rankine cycle (GT-SCO2/ORC) cogeneration system, in which the exhaust gas from gas-fired plants generates electricity through GT and ...
Gas Absorption Enhancement Mechanism in Mechanically Agitated Multiphase System: Effect of Fine Solid Particles and Interfacial Turbulence
Publisher: American Society of Civil Engineers
Abstract: To probe the particle effect on gas-liquid mass transfer in three-phase flow, a series of comparative tests was conducted in a stirred reactor with flat gas-liquid interface in which four kinds of solid particles, ...
An Efficient Hybrid Method for Multibody Dynamics Simulation Based on Absolute Nodal Coordinate Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an efficient hybrid method for dynamic analysis of a flexible multibody system. This hybrid method is the combination of a penalty and augmented Lagrangian formulation with ...
Performance Optimization Method of Composite Modified Asphalt Sealant
Publisher: American Society of Civil Engineers
Abstract: Central composite design-response surface methodology was used to determine the best content of raw materials and improve the performance of hot-poured bituminous sealant. Content range and process technology were studied ...
Determination of Critical Slip Surfaces Using Mutative Scale Chaos Optimization
Publisher: American Society of Civil Engineers
Abstract: Limit equilibrium is a common method used to analyze the stability of a slope, and minimization of the factor of safety or identification of critical slip surfaces is a classical geotechnical problem in the context of limit ...
Flow and Heat Transfer Characteristics of Single Jet Impinging on Dimpled Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on combined particle image velocimetry (PIV) and numerical simulation, the flow and heat transfer characteristics of a single jet impinging on a dimpled surface for Dj/D = 0.318, 0.5, 1.045; خ´/D = 0.1, 0.2, ...
