RISSimulation of Heat Transfer and System Behavior in a Supercritical CO2 Based Thermosyphon: Effect of Pipe Diameter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the natural convective circulation thermosyphon with supercritical CO2 flow. New heat transport model aiming at supercritical thermosyphon heat transfer and stability is ...
Modeling and H2/H∞ MIMO Control of an Earthmoving Vehicle Powertrain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Coordination of the power distribution in a Multi-Input Multi-Output (MIMO) electro-hydraulic transmission is investigated for the case of an earthmoving vehicle powertrain. A generalized model of ...
Medium-Term Multiobjective Operation Mode of Cascade Reservoirs Using Multisource Information
Publisher: ASCE
Abstract: The incorporation of information on the current system states and forecasts makes reservoir operations more efficient; however, forecast uncertainties often occur. Therefore, excellent reservoir operations should integrate ...
Generalized Multivariable Gain Scheduling With Robust Stability Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work we introduce a methodology for the design of multivariable gain-scheduled controllers for nonlinear systems and an approach for determining the local stability of a nonlinear closed ...
Perturbation Solution of Non-Newtonian Lubrication With the Convected Maxwell Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There are many studies on variations of the Maxwell model. Tichy (1996) discussed an admissible formulation of the Maxwell viscoelastic fluid model using a convected derivative and applied it ...
Flow Characteristics of Microglass Fiber Suspension in Polymeric Fluids in Spherical Gaps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study is carried out to investigate the effects of microglass fiber suspensions in the non-Newtonian fluids in a gap between an inner rotating sphere and an outer whole stationary ...
Bifurcated Forced Convective Heat Transfer of Supercritical CO2 Flow in Plane Symmetric Sudden Expansion Duct
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents a computational investigation of forced convection of supercritical CO2 flow in plane symmetric sudden expansion duct at an expansion ratio of 2 in flow asymmetric regime. ...
Engineering Properties and Micropore Structure of Clay-Based Foamed Lightweight Soil
Publisher: ASCE
Abstract: Foam lightweight soil (FLS) has been widely used in geotechnical engineering because of their high strength, low density, and thermal insulation. However, few scholars have researched its application to subgrade engineering, ...
Mediating Effect of Risk Propensity between Personality Traits and Unsafe Behavioral Intention of Construction Workers
Publisher: ASCE
Abstract: The construction industry has the highest number of casualties per accident, and workers at construction sites are vulnerable to accidents. Current research on unsafe behavior mainly focuses on behavior-based safety at the ...
Randomness and Similarity of Concrete Permeability in a Natural Tidal Environment
Publisher: ASCE
Abstract: This work first analyzes the time-dependent property of average concrete permeability by the relative decline ratio and proposes an analysis method for the randomness of time-dependent variables. Then, based on exposure ...
