The turbulent mean-velocity profile: it is all in the spectrum
Gustavo Gioia, Nicholas Guttenberg, Nigel Goldenfeld +1
It has long been surmised that the mean-velocity profile (MVP) of a pipe flow is closely related to the spectrum of turbulent energy. Here we perform a spectral analysis to identif…

Molecular Dynamics on Diffusive Time Scales from the Phase Field Crystal Equation
Pak Yuen Chan, Nigel Goldenfeld, Jon Dantzig
We extend the phase field crystal model to accommodate exact atomic configurations and vacancies by requiring the order parameter to be non-negative. The resulting theory dictates…
