Abstract

Fluctuating velocities and pressures at selected points of an oscillated laminar flow are recorded and processed to provide the statistical correlations of the transport equations for kinetic energy, helicity and enstrophy. The primitive variables solver uses UNIFAES discretization for the advective and viscous terms. Such scheme is generalized by making explicit the space derivatives employed in the solver, allowing its use in the calculation of the various correlations, in parallel with second order and fourth order central differencing schemes.

Keywords
