Atwood effects on nonlocality of the scalar transport closure in three-dimensional Rayleigh-Taylor mixing
Dana Lynn Ona-Lansigan Lavacot, Ali Mani, Brandon E. Morgan
The importance of nonlocality is assessed in modeling mean scalar transport for turbulent Rayleigh-Taylor (RT) mixing at different Atwood numbers. Building on the two-dimensional i…

Techniques for improved statistical convergence in quantification of eddy diffusivity moments
Dana Lynn Ona-Lansigan Lavacot, Jessie Liu, Brandon E. Morgan +1
While recent approaches, such as the macroscopic forcing method (MFM) or Green's function-based approaches, can be used to compute Reynolds-averaged Navier--Stokes closure operator…
