Measurements of Conditional Velocities in Turbulent Premixed Flames by Simultaneous OH PLIF and PIV
Joint velocity/scalar imaging measurements are performed in turbulent premixed natural-gas/air flames to better characterize the turbulent flux of mean reaction progress variable, ru0c0. Simultaneous two-dimensional measurements of the velocity field and the relative OH concentration are obtained by particle image velocimetry (PIV) and planar laser-induced fluorescence (PLIF) of the OH radical,...
متن کاملDiagnostics of Reactive Zone in Premixed Flames via Acetone-OH Simultaneous PLIF
Imaging scheme based on Acetone-OH simultaneous PLIF (Planer Laser-Induced Fluorescence) is applied for diagnostics of reactive zone over the premixed flames and the reactive zone imaging are demonstrated for turbulent premixed flame conditions. In the present study, visualization of reactive zone is brought by simultaneous measurement of unburned zone through acetone (seeded into the fuel flow...
متن کاملRegimes of Non-premixed Flame-vortex Interactions
Detailed studies of flame-vortex interactions are extremely valuable to improve our understanding of turbulent combustion regimes. Combined experimental and numerical studies have already been performed in the premixed case during previous investigations. Therefore, we decided to carry out a detailed experimental investigation on the regimes observed during interaction of a vortex ring and a no...
متن کاملMultiscalar imaging in partially premixed jet flames with argon dilution
Simultaneous imaging of depolarized and polarized Rayleigh scattering combined with OH-LIF and two-photon CO-LIF provides two-dimensional measurements of mixture fraction, temperature, scalar dissipation rate, and the forward reaction rate of the reaction CO+ OH = CO2 + H in turbulent partially premixed flames. The concept of the three-scalar technique for determining the mixture fraction using...
متن کاملAnalysis of a turbulent jet mixing flow by using a PIV-PLIF combined system
Abs ract : In the present paper, the development of a high-resolution PIV-PLIF combined system for the simultaneous measurements of velocity and passive scalar concentration fields is described. The high-resolution PIV-PLIF combined system is used to perform the simultaneous whole-field measurements of velocity and concentration in the near field of a turbulent jet mixing flow. The characterist...
