Triple Doppler

Laser Doppler Velocimetry measurements were performed on a TARS in a cold-flow test rig that simulates an identical hot combustion rig. Axial and tangential velocity mapping of the flow in different cross-sectional planes and along a centerline streamwise plane revealed several important flow structures in the triple annular swirling flow with co-swirling and counter-swirling cases. An axisym-metric recirculation zone was formed in the center of the flow, but the outer... 

Rotational polarisation and translational anisotropy in the recoiling fragments have a profound influence on the intensity distributions in their Doppler resolved LIF excitation (or spontaneous fluorescence) spectra [6] or their multiple photon ionisation spectra [41]. Analysis of the Doppler resolved LIF spectra has provided a powerful method for determining ea( of the three 2-vector correlations as well as their mutual correlation ( p(jjp),kV ) (cf, the triple vector correlations (k, k, ) found in the CS/CH3I full colfision system).
