RISExperiments on Supersonic Boundary-Layer Separation in Three Dimensions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A detailed experimental study of three-dimensional separation in supersonic flow is described. Three-dimensional wedges affixed to flat plates were used to generate the flow fields that were used ...
Application of Rainbow Thermometry to the Study of Fuel Droplet Heat-Up and Evaporation Characteristics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Advanced, nonintrusive, laser-based diagnostics are being developed for simultaneously measuring the size, velocity, temperature, and instantaneous regression rates of vaporizing/burning fuel droplets ...
Experiments on Spray Interactions in the Wake of a Bluff Body
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamics of spray drop interaction within the turbulent wake of a bluff body were investigated using the Aerometrics Phase Doppler Particle Analyzer, which determines both drop size and ...
The Effect of Swirl on the Velocity and Turbulence Fields of a Liquid Spray
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The work reports an experimental study of the effect of swirl on the structure of a liquid spray, i.e., on the behavior of drops and their interaction with the gaseous phase, and on the ...
An Instrument for Spray Droplet Size and Velocity Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laser light scattering techniques that measure the size of single droplets at a time have experienced difficulties when applied to high number density sprays. This problem has been alleviated ...
A Theoretical and Experimental Study of the Characterization of Bubbles Using Light Scattering Interferometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work details the theoretical and experimental research undertaken to determine the size and morphology of bubbles, and their dynamic characteristics such as velocity, number density, ...
An Exploratory Study of Soot Sample Integrity and Probe Perturbation in a Swirl-Stabilized Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In-flame measurements of soot particulate using conventional extractive and nonintrusive optical probes are compared for a swirl-stabilized combustor. Except for large (∼5μm) particulate present in ...
Particle Diagnostics and Turbulence Measurements in a Confined Isothermal Liquid Spray
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work reports an experimental study of the behavior and structure of a liquid spray immersed in a strong swirling field. In order to simulate some of the aerodynamic conditions experienced ...
Rapid Characterization of Fuel Atomizers Using an Optical Patternator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Planar laser scattering (PLS) and planar laser-induced fluorescence (PLIF) techniques are currently being used for rapid characterization of fuel sprays associated with gas turbine atomizers, diesel ...
Spray Characterization and Turbulence Properties in an Isothermal Spray With Swirl
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work reports an experimental study of the effect of swirl on the dynamic behavior of drops and on the velocity and turbulence fields of an isothermal spray using a two-component ...
