Tweed and wireframe: accelerated relaxation algorithms for multigrid solution of elliptic PDEs on stretched structured grids
Thomas Bewley, Ali Mashayek, Daniele Cavaglieri +1
Two new relaxation schemes are proposed for the smoothing step in the geometric multigrid solution of PDEs on 2D and 3D stretched structured grids. The new schemes are characterize…

Goldilocks mixing in oceanic shear-induced turbulent overturns
A. Mashayek1, C. P. Caulfield2, 3 +1
We present a new physically-motivated parameterization, based on the ratio of Thorpe and Ozmidov scales, for the irreversible turbulent flux coefficient $Γ_{\mathcal M}= {\mathcal…

Surface reflection of bottom generated oceanic lee waves
Lois Baker, Ali Mashayek
Lee waves generated by stratified flow over rough bottom topography in the ocean extract momentum and energy from the geostrophic flow, causing drag and enhancing turbulence and mi…
