Analysis of high-order velocity moments in a strained channel flow
S. V. Poroseva, S. M. Murman
In the current study, model expressions for fifth-order velocity moments obtained from the truncated Gram-Charlier series expansions model for a turbulent flow field probability de…

Validation of a new k-epsilon model with the pressure diffusion effects in separated flows
Svetlana V. Poroseva, Gianluca Iaccarino
The contribution of the "rapid" part of the pressure diffusion to the turbulent kinetic energy balance is analyzed, and a new model to describe its effect is suggested. A new trans…

Modeling the "rapid" part of the velocity/pressure-gradient correlation in inhomogeneous turbulent flows
Svetlana V. Poroseva
A new model for the "rapid" part of the velocity/pressure-gradient correlation in the Reynolds averaged Navier-Stokes equations is suggested. It is shown that in an inhomogeneous i…
