RISObserving Local-Scale Variability of Near-Surface Temperature and Humidity Using a Wireless Sensor Network
Publisher: American Meteorological Society
Abstract: n this paper the influence of surface type, wind speed, and other environmental conditions on near-surface air temperature, specific humidity, and surface temperature is studied. A wireless sensor network consisting of 13 ...
Location and Magnitude of Heat Sources in Solid Oxide Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The correct prediction of the temperature distribution is a prerequisite for the reliable determination of species and current distributions in any solid oxide fuel cell (SOFC) model. It is ...
Impact of the Temperature Profile on Thermal Stress in a Tubular Solid Oxide Fuel Cell
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The knowledge of the stress distribution in the ceramic components of a solid oxide fuel cell (SOFC) is a prerequisite for assessing the risk of failure due to crack formation as well as ...
Investigation of Lean Premixed Swirl Stabilized Hydrogen Burner With Axial Air Injection Using OH PLIF Imaging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the context of lean premixed combustion, the prevention of upstream flame propagation in the premixing zone, referred to as flashback (FB), is a crucial challenge related to the application of hydrogen as a fuel for gas ...
Sensitivity Analysis of Phase Change Modeling for Non-Ideal Fluids in Turbomachinery Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Investigating phase change phenomena with numerical methods reveals a strong dependence on the selected model equations. The phase change from gas to liquid, or condensation, is primarily governed by nucleation ...
Modeling of Polymer Seals at High Cryogenic Temperatures Across the Glass Transition
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. The design of polymer valve seals is challenging especially for cryogenic applications due to a significant stiffening of the polymer material when the temperature falls below its glass transition temperature. ...
Residence Time Distribution in a Swirling Flow at Nonreacting, Reacting, and Steam Diluted Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Residence time distributions in a swirling, premixed combustor flow are determined by means of tracer experiments and a reactor network model. The measurements were conducted at nonreacting, reacting, and steamdiluted ...
A High Throughput System for Long Term Application of Intermittent Cyclic Hydrostatic Pressure on Cells in Culture
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The process of bone remodeling is governed by mechanical stresses and strains. Studies on the effects of mechanical stimulation on cell response are often difficult to compare as the nature ...
Laminar Burning Velocities and Emissions of Hydrogen–Methane–Air–Steam Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Humidified gas turbines using steam generated from excess heat feature increased cycle efficiencies. Injecting the steam into the combustor reduces NOx emissions, flame temperatures, and burning velocities, promising a ...
New Developments of the Boundary Element Method for Underground Constructions
Publisher: American Society of Civil Engineers
Abstract: In this paper, an innovative modeling approach is presented for the simulation of underground construction with the emphasis on tunneling. The boundary element method (BEM) is used, and the theoretical background is discussed ...
