RISResponse of Soot Temperature to Unsteady Inlet Airflow Under Modulated Condition and Naturally Occurring Combustion Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The response of soot temperature to unsteady inlet airflow is characterized using pyrometry. The unsteady inlet airflow is achieved by either modulating inlet air or naturally occurring unstable flame, running on a jet ...
Spatiotemporal Distribution of Soot Temperature for Flames Using Optical Pyrometry Under Unsteady Inlet Airflow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two pyrometric tools for measuring soot temperature response in fuel-rich flames under unsteady inlet airflow conditions are developed. High-speed pyrometry using a high-speed color camera is used in producing soot temperature ...
Identification of Non Gaussian Stochastic System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a method to identify nonGaussian random noise in an unknown system through the use of a modified system identification (ID) technique in the stochastic domain, which is based on a recently developed ...
Liquid Jets in Subsonic Air Crossflow at Elevated Pressure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The breakup, penetration, droplet size, and size distribution of a Jet A1 fuel in air crossflow has been investigated with focus given to the impact of surrounding air pressure. Data have been collected by particle Doppler ...
A Detailed Comparison of a Range of Three-Dimensional Models of the M2 Tide in the Faeroe–Shetland Channel and Northern North Sea
Publisher: American Meteorological Society
Abstract: A three-dimensional hydrodynamic model of the Faeroe?Shetland Channel and northern North Sea is used to investigate the spatial variability of M2 tidal elevations and currents in the region. This area is chosen because it ...
Nondestructive Integrity Evaluation of Soil Nails Using Longitudinal Waves
Publisher: American Society of Civil Engineers
Abstract: Structural failures of soil-nailed structures occasionally occur due to the poor integrity of soil nails. The objective of this study was to evaluate soil nail integrity by estimating the installed length and grouted ratio ...
Effects of Mechanical Preloads on the Rotordynamic Performance of a Rotor Supported on Three Pad Gas Foil Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the rotordynamic performance measurements and model predictions of a rotor supported on threepad gas foil journal bearings (GFJBs) with various mechanical preloads. The rotor with its length of 240 mm, ...
Intradiscal Microprobe With a Vibrational Optical Fiber for Diagnosis and Thermal Therapy of Discogenic Pain Due to an Annular Fissure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Major studies have shown that discogenic pain is the most common cause of chronic lower back pain, accounting for 40% of all the causes. Provocation discography—inducing pains by pressing nerve structures around the ...
Numerical Verification of the Schroeder–Webster Surface Types and Friction Compensation Models for a Metallic Specimen in Axisymmetric Compression Test
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Three types of surfaces in the Schroeder–Webster (SW) theory, i.e., sliding, mixed, and sticking surfaces, have been verified via finite element analysis of an axisymmetric compression test for a metallic specimen. Judging ...
Electrical Reliability of Flexible Silicon Package Integrated on Polymer Substrate During Repeated Bending Deformations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Although the reliability of flexible electronics during bending deformation is of great interest nowadays, the mechanical reliability that has mainly been investigated is of single electronic components or simple devices, ...
