A Fourier/Modal-Spectral-Element Method for the Simulation of High-Reynolds Number Incompressible Stratified Flows in Domains with a Single Non-Periodic Direction
Nidia Reyes-Gil, Greg Thomsen, Kristopher Rowe +1
We present the components of a high-order accurate Navier-Stokes solver designed to simulate high-Reynolds-number stratified flows. The proposed numerical model addresses some of t…
Formation and evolution of turbulence in convectively unstable internal solitary waves of depression shoaling over gentle slopes in the South China Sea
Tilemachos Bolioudakis, Theodoros Diamantopoulos, Peter J. Diamessis +4
The shoaling of high-amplitude Internal Solitary Waves (ISWs) of depression in the South China Sea (SCS) is examined through large-scale parallel turbulence-resolving high-accuracy…
Experimental study of the initial growth of a localized turbulent patch in a stably stratified fluid
Lilly Verso, Maarten van Reeuwijk, Roi Gurka +3
We present a laboratory experiment of the growth of a turbulent patch in a stably stratified fluid, due to a localized source of turbulence, generated by an oscillating grid. Synch…
A deflated Schur complement method for the iterative solution of a high-order discontinuous element discretization of the Poisson equation
Sumedh Joshi, Peter Diamessis
A combination of block-Jacobi and deflation preconditioning is used to solve a high-order discontinuous element-based collocation discretization of the Schur complement of the Pois…
Deflation-accelerated preconditioning of the Poisson-Neumann Schur problem on long domains with a high-order discontinuous element-based collocation method
Sumedh M. Joshi, Greg N. Thomsen, Peter J. Diamessis
A combination of block-Jacobi and deflation preconditioning is used to solve a high-order discontinuous collocation-based discretization of the Schur complement of the Poisson-Neum…
A post-processing technique for stabilizing the discontinuous pressure projection operator in marginally-resolved incompressible inviscid flow
Sumedh M. Joshi, Peter J. Diamessis, Derek T. Steinmoeller +2
A method for post-processing the velocity after a pressure projection is developed that helps to maintain stability in an under-resolved, inviscid, discontinuous element-based simu…
