With velocity, correlations scattering data

Time- and space-resolved fluctuation data for flame gas temperature and major species densities have been obtained from Raman scattering and from stronger inelastic scattering processes. When combined with information about velocity from laser velocimetry, these data and their correlations provide key new information for flow field and combustion field modeling. 

Thus, the corrections to the velocities Cpb (r) and Csb (r) on the first iteration can be obtained by correlating the back-propagated scattered elastic field with the derivatives of the incident field U (r,t). This transformation is similar to wavefield migration described previously. Thus we see that elastic field inversion can be constructed by iterative migration of the residual elastic data. 

Thulasidas et al. [6] compared their and all other available experimental data on relative bubble velocity, m, with the literature correlations. There was a considerable scattering of the experimental data at the lower values of Ca, particularly for Ca < 10, while Bretherton s correlation was found to underpredict all the data. The results showed that m reached a limiting value of 0.58 at large values of Ca. 

Horizontal LAD channel tests show that the frictional and dynamic pressure losses within the channel are quite small. The signals are barely measurable in LH2, and the signals are small for LOX flows in excess of 2.25 kg/s. The ID model correlates with the single set of LOX channel frictional pressure drop data. Disparity is due to higher than expected screen injection velocities at the channel exit and scatter in the data.
