Parameter Estimation of the Muskingum Channel Flood-Routing Model in Ungauged Channel Reaches
Publisher: American Society of Civil Engineers
Abstract: The Muskingum model is one of the most popular models for hydrologic channel flood routing. However, as the parameters of this model are estimated by analyzing both inflow and outflow data, the application of this model ...
Evaluation for Biological Reduction of Nitrate and Perchlorate in Brine Water Using the Hydrogen-Based Membrane Biofilm Reactor
Publisher: American Society of Civil Engineers
Abstract: Whereas ion exchange is an attractive technology for treating perchlorate and nitrate in drinking water, a major disadvantage is that the resin must be regenerated using a brine, producing wastes with high concentrations ...
Performance Analysis of Parallel Mechanism Architectures for CNC Machining Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we propose a set of criteria to evaluate the performance of various parallel mechanism architectures for CNC machining applications. In the robotics literature mathematical formulations ...
Finite-Element Model to Evaluate Nonlinear Behavior of Posttensioned Composite Beams with Partial Shear Connection
Publisher: American Society of Civil Engineers
Abstract: A finite-element (FE) model to simulate nonlinear structural behavior of posttensioned composite beams with partial shear connectors is introduced in this paper. Stress-strain material models for concrete and steel are ...
Development of Gasoline Direct Injection Engine for Improving Brake Thermal Efficiency Over 44%
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study demonstrates the effects of technologies applied for the development of gasoline direct injection (GDI) engine for improving the brake thermal efficiency (BTE). The test engine has a relatively high stroke to ...
Exact Enforcement of the Causality Condition on the Aerodynamic Impulse Response Function Using a Truncated Fourier Series
Publisher: American Society of Civil Engineers
Abstract: This paper presents the exact relation between the real and imaginary parts of aerodynamic transfer functions for deriving impulse response functions that satisfy the causality condition. A truncated Fourier series is used ...
Performance Metric for Turbine Stage Under Unsteady Pulsating Flow Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a turbine stage for a vehicular turbocharger or a pulse detonation engine (PDE) system, the power extraction process is inherently unsteady due to a highly pulsating flow delivered from the upstream combustor. Characterizing ...
Performance Characterization of Twin-Scroll Turbine Stage for Vehicular Turbocharger Under Unsteady Pulsating Flow Environment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Unsteady three-dimensional computations have been implemented on a turbocharger twin-scroll turbine system (volute–turbine wheel–diffuser). The flow unsteadiness in a turbocharger turbine system is essentially driven by a ...
