Comparison of Near-Nozzle Spray Performance of Gas-to-Liquid and Jet A-1 Fuels Using Shadowgraph and Phase Doppler Anemometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The gas-to-liquid (GTL) fuel, a liquid fuel synthesized from natural gas through Fischer–Tropsch process, exhibits better combustion and, in turn, lower emission characteristics than the conventional jet fuels. However, ...
Near-Wall Velocimetry in the Impingement-Zones of a Microdroplet and a Round Jet Stream
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Near-wall fluid velocimetry in the impingement zone of a microdroplet stream on a flat surface is reported utilizing microparticle tracking velocimetry (μPTV). The results are then compared with the near-wall fluid velocimetry ...
Effect of Nanoparticles on the Fuel Properties and Spray Performance of Aviation Turbine Fuel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The influence of nanoparticles' dispersion on the physical properties of aviation fuel and its spray performance has been investigated in this work. To this end, the conventional Jet A-1 aviation fuel and its mixtures with ...
Thermodynamic Study on Blends of Hydrocarbons and Carbon Dioxide as Zeotropic Refrigerants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finding alternative refrigerants is of extreme importance to mitigate anthropogenic climate change. Among the next-generation refrigerants, hydrocarbons (HCs) are of technical interest because they are natural, efficient, ...

Experimental and Numerical Visualization of Droplet-Induced Crown Splashing Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this study was to visualize the droplet-induced crown splashing dynamics at high spatial and temporal resolutions. In this work, the effects of droplet train impingement on crown splashing dynamics were ...
Experimental and Numerical Visualization of Heat Transfer and Hydrodynamics Induced by Double Droplet Train Impingement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this study was to visualize and simulate the thermal physical process during double droplet train impingement for three different horizontal impact spacings (S = 0.65 mm, 1.2 mm and 2 mm). Two identical ...
Effect of Carbon Dioxide on the Laminar Burning Speed of Propane–Air Mixtures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This experimental research examined the effect of CO2 as a diluent on the laminar burning speed of propane–air mixtures. Combustion took place at various CO2 concentrations (0–80%), different equivalence ratios (0.7<ϕ<1.2) ...
