RISComparison 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 ...
