RISLong-to-Short Length-Scale Transition: A Stall Inception Phenomenon in an Axial Compressor With Inlet Distortion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theoretical and experimental study of stall inception processes in a three-stage low-speed axial flow compressor with inlet distortion is presented in this paper. Since inlet distortion provides ...
Warping Analysis in Laminated Object Manufacturing Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents an analysis of warping that occurs in the laminated object manufacturing process. Based on the study of thermal-mechanical behavior of the adhesive and its effect on the ...
Evaluating the Use of Nash-Sutcliffe Efficiency Coefficient in Goodness-of-Fit Measures for Daily Runoff Simulation with SWAT
Publisher: American Society of Civil Engineers
Abstract: Hydrological models must be carefully calibrated to ensure that predictions are scientifically sound and reliable. As a goodness-of-fit measure, an ideal threshold of the Nash-Sutcliffe efficiency coefficient (Ens) has ...
Shear Transfer Mechanism of Concrete Strengthened with External CFRP Strips
Publisher: American Society of Civil Engineers
Abstract: Concrete with reinforcing steel bars across a shear plane was strengthened using carbon fiber–reinforced polymer (CFRP) strips externally bonded to resist shear transfer. Specimens were designed and tested to give insight ...
Mixed-Integer Chance-Constrained Models for Ground-Water Remediation
Publisher: American Society of Civil Engineers
Abstract: Ground-water remediation optimization models were formulated using a statistical optimization methodology, chance-constrained programming (CCP), to account for uncertainty in the coefficients of the models. Several models ...
Numerical Investigation on the Self-Induced Unsteadiness in Tip Leakage Flow for a Transonic Fan Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical investigation on the self-induced unsteadiness in tip leakage flow is presented for a transonic fan rotor. NASA Rotor 67 is chosen as the computational model. It is found that ...
The Impact of Casing Groove Location on Stall Margin and Tip Clearance Flow in a Low Speed Axial Compressor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, the impact of single grooves at different locations on compressor stability and tip clearance flow are numerically and experimentally investigated. Initially, the numerical stall margin improvement (SMI) ...
Municipal Wastewater Treatment Using a UASB Coupled with Cross-Flow Membrane Filtration
Publisher: American Society of Civil Engineers
Abstract: A pilot scale up-flow anaerobic sludge blanket (UASB) coupled with cross-flow membrane filtration was used to treat low strength municipal wastewater in Singapore. The application of membrane filtration as a polishing unit ...
Lane Geometry Perception and the Characterization of Its Associated Uncertainty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses the reconstruction of down-range road geometry from imaging sensors for application to motor vehicle active safety systems. This study assumes measurements of lane marker ...
Collapse Mechanism of Reinforced Concrete Superlarge Cooling Towers Subjected to Strong Winds
Publisher: American Society of Civil Engineers
Abstract: This paper presents a numerical simulation on the collapse behavior and structural stability of a reinforced concrete superlarge cooling tower subjected to strong winds. Results demonstrated that the cooling tower locally ...
