A Note on Favre Averaging in Variable Density Flows.
PURDUE UNIV LAFAYETTE IND PROJECT SQUID HEADQUARTERS
Pagination or Media Count:
The concept of a Favre probability density function is introduced and this formalizes the definition of Favre averages in variable density flows. Current approaches to turbulence modeling suggest that it is the Favre probability density function which models in such flows. This is of particular use in the modeling of conserved scalars since the conservation equations deliver the Favre average and variance.
