MPI Parallel Implementation for Pseudo-Spectral Simulations for Turbulent Channel Flow
TLDR
This study designs and improves the spectral code by exploring parallel techniques, including domain decomposition and data transposition algorithms, and focuses particularly on the 2D domain decompositions and transpose algorithm with the non-blocking collective operations, thereby enabling latency mitigation by overlapping the computation and communication.

TLDR
This paper proposes a pipelined stencil algorithm called Pencil for distributed memory machines that applies to practical CFD problems that span multiple iteration spaces and achieves overlap by pipelining the computation and communication without sacrificing the advantage from temporal cache tiling.

An improved projection scheme applied to pseudospectral methods for the incompressible Navier-Stokes equations
TLDR
An improved projection scheme is proposed and applied to pseudospectral collocation-Chebyshev approximation for the incompressible Navier‐Stokes equations, showing that this method provides a time accuracy of the same order as the temporal scheme used for the pressure, and also improves the prediction of the velocity slip.

Turbulent Bursts in Couette-Taylor Flow.
TLDR
A mathematical model from the Navier–Stokes equations is derived using approximations based on the physical model for turbulent bursts in the three-dimensional flow between concentric, rotating cylinders (Couette-Taylor flow) to show how well the model agrees with the numerically computed velocities, how it explains correlations and other properties of the numerally computed fields, and how it makes predictions that could be tested in future experiments.
