RISResponse of a Tandem-Staged Compressor to Circumferential Inflow Distortion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tandem rotor, as a concept, promises a higher diffusion capacity than a single rotor. However, it is reported to have a lower operating range than the conventional rotor. Inflow distortion can lead to significant changes ...
Fuzzy Logic Based Controller for a Grid Connected Solid Oxide Fuel Cell Power Plant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a mathematical model of a solid oxide fuel cell (SOFC) power plant integrated in a multimachine power system. The utilization factor of a fuel stack maintains steady state by tuning the fuel valve in ...
Simultaneous Extraction of Clean Coal and Rare Earth Elements From Coal Tailings Using Alkali-Acid Leaching Process
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: With the supply restriction from traditional rare earth deposits, alternative sources of rare earth elements (REEs) such as coal are being studied. The United States National Energy Technology Laboratory has identified US ...
Numerical and Experimental Investigation of a Volumetric Resistance Blower Performance and Its Optimization for Portable Computing Device Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present our results on a relatively new kind of blower called Volumetric Resistance Blower (VRB) for cooling of portable computing platforms like laptop computers. The VRB performance was modeled numerically ...
Experimental Study for the Enhancement of Thermal Efficiency and Development of Nusselt Number Correlation for the Roughened Collector of Solar Air Heater
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The solar air heater’s thermal efficiency is relatively poor owing to the flat collector surface. This article’s primary objective is to increase the collectors’ thermal efficiency of rectangular ducts of solar air heater ...
A Numerical Study on MicrogapBased Focal Brain Cooling Device to Mitigate Hotspot for the Treatment of Epileptic Seizure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Epilepsy is a common chronic neurological disorder characterized by abnormally excessive and synchronized brain cell activities causing seizures. For proper functioning of the brain, epilepsy should be diagnosed with ...
Understanding the Effect of Three-Dimensional Design in Tandem Blade
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to maximize the pressure ratio and efficiency, compressor designers have tried several unconventional design approaches. Tandem blading is one such unconventional design that promises a higher pressure ratio per ...
Numerical Analysis of a Two-Phase Turbine: A Comparative Study Between Barotropic and Mixture Models
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase turbines offer the potential to significantly enhance the performance of power generation and refrigeration systems. However, their development has been hindered by comparatively lower efficiencies resulting from ...
Improved Rating System for Hazard Assessment Related to Subsurface Migration of Landfill Gas from Municipal Solid Waste Landfills and Dumps
Publisher: American Society of Civil Engineers
Abstract: Among the hazards from landfill gas (LFG), explosions due to methane migrated from municipal solid waste (MSW) sites have resulted in evacuation, property damage, and injuries and deaths for human beings. This study develops ...
Aerodynamics of Sweep in a Tandem-Bladed Subsonic Axial Compressor Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present numerical investigation aims to understand the effect of the chordwise sweep on the performance of a tandem rotor. In a tandem compressor rotor, diffusion is achieved through two smaller airfoils, which are ...
