RISDecision-Based Approach for Reliability Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We propose a decision-based approach for reliability design when there is insufficient information for constructing probabilistic models. The approach enables a designer to perform reliability-cost ...
Integrated Power and Thermal Management System for A Hybrid-Electric Aircraft: Integrated Modeling and Passive Cooling Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Aircraft electrification introduces challenges in power and thermal management. In a hybrid-electric aircraft (HEA), the additional heat loads generated by the high-power electrical components in the propulsion system can ...
A Single-Loop Approach for System Reliability-Based Design Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An efficient approach for series system reliability-based design optimization (RBDO) is presented. The key idea is to apportion optimally the system reliability among the failure modes by considering ...
A Review of the Turbine Cooling Fraction for Very High Turbine Entry Temperature Helium Gas Turbine Cycles for Generation IV Reactor Power Plants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The potential for high turbine entry temperature (TETs) turbines for nuclear power plants (NPPs) requires improved materials and sophisticated cooling. Cooling is critical for maintaining mechanical integrity of the turbine ...
Analyses of the Control System Strategies and Methodology for Part Power Control of the Simple and Intercooled Recuperated Brayton Helium Gas Turbine Cycles for Generation IV Nuclear Power Plants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An important requirement for Generation IV Nuclear Power Plant (NPP) design is the control system, which enables part power operability. The choices of control system methods must ensure variation of load without severe ...
Analyses of the Load Following Capabilities of Brayton Helium Gas Turbine Cycles for Generation IV Nuclear Power Plants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The control system for generation IV nuclear power plant (NPP) design must ensure load variation when changes to critical parameters affect grid demand, plant efficiency, and component integrity. The objective of this study ...
Analyses of a High Pressure Ratio Intercooled Direct Brayton Helium Gas Turbine Cycle for Generation IV Reactor Power Plants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The intercooled cycle (IC) as an alternative to the simple cycle recuperated (SCR) and intercooled cycle recuperated (ICR) is yet to be fully analyzed for the purpose of assessing its viability for utilization within ...
Axial and Secondary Flow Study in a 90 Deg Bifurcation Under Pulsating Conditions Using PIV
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Both axial and secondary flow were experimentally studied in a 90-degree bifurcation of square tubes, under pulsating conditions and equal branch flow rates. The examined peak Reynolds number ...
An Efficient Re-Analysis Methodology for Probabilistic Vibration of Large-Scale Structures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Probabilistic analysis and design of large-scale structures requires repeated finite-element analyses of large models, and each analysis is expensive. This paper presents a methodology for probabilistic ...
Limitations of Pareto Front in Design Under Uncertainty and Their Reconciliation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engineering design reconciles design constraints with decision maker (DM) preferences. The task of eliciting and encoding decision maker preferences is, however, extremely difficult. A Pareto front representing the locus ...
