RISExploiting Stochastic Resonance Principles to Influence the Efficiency of a Torsional-Flutter Energy Harvester in Turbulent Winds1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wind energy harvesters are emerging as a viable alternative to standard, large horizontal-axis wind turbines. This study continues a recent investigation on the operational features of a torsional-flutter-based apparatus, ...
Comparison of Reduced-Order Models to Analyze the Dynamics of a Tall Building under the Effects of Along-Wind Loading Variability
Publisher: American Society of Civil Engineers
Abstract: Aeroelastic vibration, influenced by wind load effects, is relevant to the structural design of tall buildings. In the framework of performance-based design of wind load–sensitive structures, the effects induced by variability ...
Planning for Sustainable Land-Use Changes: Indications from an Assessment of Soil Consumption in a Polycentric Region
Publisher: American Society of Civil Engineers
Abstract: The present study investigates the relationship between land-use changes and soil capability in a polycentric region of northern Italy over two distinct periods: a dense and compact phase of urban growth observed after the ...
Adjoint Methods as Design Tools in Thermoacoustics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a thermoacoustic system, such as a flame in a combustor, heat release oscillations couple with acoustic pressure oscillations. If the heat release is sufficiently in phase with the pressure, these oscillations can grow, ...
Unified Stochastic Dynamic and Damage Cost Model for the Structural Analysis of Tall Buildings in Thunderstorm-Like Winds
Publisher: American Society of Civil Engineers
Abstract: Stochastic calculus has been used traditionally in the field of finance since it can model variability in the stock market and fluctuations of monetary variables (assets, savings, etc.) in the financial sector. Stochastic ...

Improving Output Power of a Torsional-Flutter Harvester in Stochastic Thunderstorms by Duffing—Van Der Pol Restoring Torque1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Wind energy harvesters are usually designed to operate in the low wind speed range. They rely on smaller swept areas, as a complement to larger horizontal-axis wind turbines. A torsional-flutter-based apparatus is investigated ...
Effects of Rotation and Buoyancy Forces on the Flow Field Behavior Inside a Triangular Rib Roughened Channel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow field inside a triangular cooling channel for the leading edge of a gas turbine blade has been investigated. The efforts were focused on the investigation of the interaction between effects of rotation, of buoyancy ...
Life-Cycle Cost Analysis of a Point-Like Structure Subjected to Tornadic Wind Loads
Publisher: ASCE
Abstract: To quantify the monetary losses associated with damages induced by tornado wind storms, a numerical performance-based engineering framework complete with dynamic simulation of tornado-like wind fields, calculation of ...
An Elasto-Plastic Reformulation of the Theory of Critical Distances to Estimate Lifetime of Notched Components Failing in the Low/Medium-Cycle Fatigue Regime
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper is concerned with a novel elasto-plastic reformulation of the Theory of Critical Distances (TCD) specifically devised to estimate lifetime of notched metallic materials (ferrous and ...
