The liquid turbulent flux
closure  is calculated by means of a gradient closure, the discretization of the divergence terms was solved with a Gamma NVD scheme, and a first order Euler scheme is applied for time derivative terms.
We model the turbulent flux
and stress with the eddy viscosity assumption:
where [??]([eta]) is the Favre PDF of mixture fraction and <[u".sub.i] [y".sub.[kappa]] | [eta]> is the conditional turbulent flux
. Using these approximations, the conditional species transport equation takes the form:
describes the turbulent flux
of energy K = 1/2 [u.sup.2] and
The coming years will be exciting, both for the journal and for [T.sup.2]M, as our field is in turbulent flux
, moving from traditional 'transport history' towards a 'history of mobility' of which the content and the borders have not yet been explored.
The basis for both approaches is the estimation of the turbulent flux
profiles by a function that is usually proportional to the vertical gradient of the transported variable.

where LHS is the local TKE budget, the two first RHS terms are the shear production terms, the third RHS term is the buoyant production/destruction of TKE, the fourth RHS term is turbulent transport of turbulence, with [bar.w'E'] being the local turbulent flux
of TKE, and the last RHS term is the viscous dissipation of TKE.
There is a general lack of the energy balance closure at eddy covariance sites, which could be attributed to several hypotheses , including (1) a systematic bias in instrumentation, (2) neglected energy sinks, (3) the loss of low or high frequency contributions to the turbulent flux
, (4) neglected advection of scalars, and (5) sampling errors associated with different measurement source areas for terms in energy balance components.
