Simple shear flow is characterized by a linear profile of the velocity field (the shear rate, dv/dy, is constant).
He proposed a method to replace the average phase velocity vp(x,t) with a size-conditioned velocity field.
In this case, he showed that, because the advective term features a size-dependent velocity field, the equation presents no diffusive flux in physical space.
profile directly depends on the path-line and velocity field calculated by the code.
The velocity field calculations are the same for both the QMOM and FCMOM method; however, the d10 contours are slightly different because of the possible inaccuracy in the calculation of moments.،In his thesis research (Corrsin, 1947), in addition to his important observa- tions of the turbulent velocity field, he was - for the first time - able to measure the turbulent heat flux and, therefore, to present data to test some of the exist- ing theories for turbulent heat transfer.
That is, given the statistical properties of the Eulerian velocity field, say u(x, t), what are the statistical properties of interest of the Lagrangian field, in particular the mean-square displacement and velocity time autocorrelation.
Assuming that, for large time sep- arations, the Eulerian velocity field becomes independent of the Lagrangian displacements ?
properties of the velocity field.
Detailed measurements were made of the velocity field and temperature field statistics, including joint tem- perature/velocity statistics, spectra, autocorrelations, microscales and integral
