RISOptimum Geometry Design of Double‐Layer Space Trusses
Publisher: American Society of Civil Engineers
Abstract: In recent years, extensive and increasing use has been made of space trusses, especially in the form of double‐layer space grids. In the design, almost unlimited possibilities exist in practice for the choice of geometry ...
Analysis of Residual and Operational Thermal Stresses in a Planar SOFC
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A structural model has been developed for analysis of residual stresses for anodeand electrolytesupported planar solid oxide fuel cells (SOFC). This model was also used for analysis of thermally induced stresses during ...
Modeling of Overpotentials in an Anode-Supported Planar SOFC Using a Detailed Simulation Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper results from a parameter study of an anode-supported solid oxide fuel cell (SOFC) are presented. The effects on performance, current-voltage (I-V) characteristics, polarization ...
Experimental Investigation and Theoretical Predication of Flutter Behavior of a Plane Cascade in Low Speed Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Institute of Aeroelasticity operates a test facility which enables aeroelastic investigations of plane cascades in low-speed flow. The test stand serves as a pilot facility to develop tools ...
Estimates of Characteristic Times for Precipitation Scavenging
Publisher: American Meteorological Society
Abstract: We address the problem of using climatological data to estimate residence times in the atmosphere of particles subjected to precipitation scavenging. Basic parameters are the scavenging coefficient ?, the rainfall intensity ...
Application of an Advanced Creep–Fatigue Procedure for Flexible Design of Steam Turbine Rotors Based on Fracture Mechanics Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The demand for steam turbine components is driven not only by high efficiency but also by high plant operational flexibility. Steam turbine rotors are therefore exposed to increased temperatures and increased number of ...
A Follow-the-Leader Approach to Serpentine Robot Motion Planning
Publisher: American Society of Civil Engineers
Abstract: Serpentine robots offer advantages over traditional mobile robots and robot arms because they have enhanced flexibility and reachability, especially in convoluted environments. These robots are well suited to inspect large ...
Modeling Micro Mass and Heat Transfer for Gases Using Extended Continuum Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents recent contributions to the development of macroscopic continuum transport equations for micro gas flows and heat transfers. Within the kinetic theory of gases, a combination ...
Probabilistic Nonlocal Damage Model for Continua with Random Field Properties
Publisher: American Society of Civil Engineers
Abstract: Nonlocal continuum damage mechanics and random field theory are used to model the stochastic damage behavior of a strain‐softening material with random field properties. The randomness in the damage process is introduced ...
Intertemporal Preferences of Potable Water Supply Consumers
Publisher: American Society of Civil Engineers
Abstract: This research explores potable water consumers’ willingness to pay to fund up-front investments in their potable water supply services (PWSSs), which will reduce rates in the longer term. An online survey of 1,970 New ...
