... biofuel gas turbines laser Doppler anemometry nozzles The significance of aviation fuels derived from nonpetroleum sources continues to increase as issues related to the security of supply and the depletion of conventional feedstocks persist. The Canadian Air Force (CAF) is participating...

... carried out using a laser Doppler anemometry system in an experimental rig, which consists of a 1:1 model of the front bearing chamber of an aero engine. Tests were carried out at real operating conditions both for the air-flow and for the lubricant oil-flow and for a range of shaft rotating speeds...

... was characterized regarding droplet slip velocities with an extended laser Doppler anemometry technique. The comparison between numerical and experimental results shows that the droplet slip velocities in the macroscopic reaction zone are within the transition range from an envelope to a wake flame. It is concluded...

... the combustion chamber using laser Doppler anemometry (LDA). The experimental data were compared to the numerical results using four two-equation turbulence models (standard k - ε , realizable k - ε , Wilcox k - ω , and SST k - ω models). All the investigated turbulence models well predicted the global...

...: the dimensionless flow coefficient was used to evaluate the global breathability of the intake system, while the laser doppler anemometry (LDA) technique was employed to define the flow structure within the combustion chamber. The analysis gave evidence of two contrarotating vortices with axes parallel...
