RISAcoustic Pyrometry Robustness to Time-of-Flight Estimation Errors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Acoustic pyrometry is a widely used technique for contactless temperature measurement. It may be used in several applications, especially when high temperatures and harsh environments are involved. For instance, it has ...
Impact of Forecast Uncertainty on Wind Farm Profitability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The great amount of support schemes that initially fueled the fast and often uncontrollable, renewable energy sources (RESs) growth have been strongly reduced or revoked in many countries. Currently, the general trend is ...
An Experimental Methodology for the Reconstruction of Three Dimensional Acoustic Pressure Fields in Ducts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The claim for low emission engines, imposed by strict environmental legislation, has prompted the aeronautical industry to reduce both noise emission and pollution by using lean combustion technology. These engines are ...
Off-Design of a Pumped Thermal Energy Storage Based on Closed Brayton Cycles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The growth of renewable energy source requires reliable, durable, and cheap storage technologies. In this field, the pumped thermal energy storage (PTES) is drawing some interest as it appears not to be affected by ...
Small Wind Turbines in the Built Environment: Influence of Flow Inclination on the Potential Energy Yield
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Increasing interest is being paid by architects, project developers and local governments to understanding where small wind turbines can effectively be exploited to provide delocalized power in the built environment. The ...
Pyrometric Estimation of Exhaust Valve Temperature of an Internal Combustion Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The estimation of exhaust valve temperature of an internal combustion engine during its operation would be very useful for a more reliable and accurate design of valves and, more in general, of the whole valvetrain system. ...
Blade Design Criteria to Compensate the Flow Curvature Effects in H Darrieus Wind Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Darrieus wind turbines are experiencing a renewed interest in the wind energy scenario, in particular, whenever small and mediumsize installations are considered. In these contexts, the average wind speeds are generally ...
Development of an Innovative Multisensor Waveguide Probe With Improved Measurement Capabilities
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Currently, waveguide probes are widely used in several turbomachinery applications ranging from the analysis of flow instabilities to the investigation of thermoacoustic phenomena. There are many advantages to using a ...
Development of a Fast-Response Aerodynamic Pressure Probe Based on a Waveguide Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Currently, fast-response aerodynamic probes are widely used for advanced experimental investigations in turbomachinery applications. The most common configuration is a virtual three-hole probe. This solution is a good ...
Aerodynamics of Darrieus Wind Turbines Airfoils: The Impact of Pitching Moment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent studies have demonstrated that, when rotating around an axis orthogonal to the flow direction, airfoils are virtually transformed into equivalent airfoils with a camber line defined by their arc of rotation. In these ...
