RISExergy Costing in Exergoeconomics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Existing methods of exergoeconomic analysis and optimization of energy systems operate with single average or marginal cost values per exergy unit for each material stream in the system being ...
Velocity Fields of Nonpremixed Bluff-Body Stabilized Flames
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The velocity fields of nonpremixed circular-disk stabilized flames are measured by a two-component laser Doppler velocimeter. The results are presented in different flow regimes: prepenetration, ...
Controlling Secondary-Flow Structure by Leading-Edge Airfoil Fillet and Inlet Swirl to Reduce Aerodynamic Loss and Surface Heat Transfer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Computations, based on the ensemble-averaged compressible Navier-Stokes equations closed by the shear-stress transport (SST) turbulence model, were performed to investigate the effects of leading-edge ...
Identification of Multi-Input Multi-Output Linear Systems From Frequency Response Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A procedure for identifying a multi-input multi-output linear system from frequency response data is developed. Individual transfer functions from individual input to individual output are identified ...
Correlations of Critical Froude Number for Annular-Rimming Flow in Rotating Heat Pipes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The behavior of flow within a rotating finite length cylinder has been investigated. For low rotational speeds, the flow is characterized by a non-uniform thickness i.e., rimming flow. Above a ...
Exergoeconomic Evaluation of a KRW-Based IGCC Power Plant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a study supported by the U. S. Department of Energy, several design configurations of Kellogg-Rust-Westinghouse (KRW)-based Integrated Gasification-Combined-Cycle (IGCC) power plants were developed. ...
Exergetic Comparison of Two KRW-Based IGCC Power Plants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In studies supported by the U.S. Department of Energy and the Electric Power Research Institute, several design configurations of Kellogg-Rust-Westinghouse (KRW)-based Integrated Gasification-Combined-Cycle ...
Interaction of Metal and Other Contaminants Present in Sludge and Soil
Publisher: American Society of Civil Engineers
Abstract: Laboratory experiments were conducted to evaluate the interaction of metals (As, Cd, Cr, Cu, Pb, and Ni) and nitrate-N present in municipal sludge with a soil sample. The soil selected for this experiment was Menfro silt ...
Contractor’s Opportunistic Bidding Behavior and Equilibrium Price Level in the Construction Market
Publisher: American Society of Civil Engineers
Abstract: The competitive bidding system has been to blame for abnormally low bids, which are considered as one of the main causes of poor project quality. Previous studies have regarded the pricing of bidders as an optimum decision ...
Development of a Natural Treatment System for Stream Water Purification: Mechanisms and Environmental Impacts Evaluation
Publisher: American Society of Civil Engineers
Abstract: A constructed wetland type natural treatment system was built in southern Taiwan for stream water purification and natural habitat creation. The system influent (influent rate =
