MPI Parallel Implementation for Pseudo-Spectral Simulations for Turbulent Channel Flow
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.
Numerical Simulations of Heat Transfer Performance of Taylor–Couette Flow in Slit Model
A partially averaged Navier–Stokes model is used to simulate the fluid field in the coaxial cylindrical gap, and the reliability of numerical simulation is verified by comparing with the particle
Phase-field simulation of core-annular pipe flow
Pencil: A Pipelined Algorithm for Distributed Stencils
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.
Nonlinear waves in stratified Taylor--Couette flow. Part 2. Buoyancy flux
This paper is the second part of a two-fold study of mixing, i.e. the formation of layers and upwelling of buoyancy, in axially stratified Taylor--Couette flow, with fixed outer cylinder. In a first


Simulation of Taylor-Couette flow. Part 1. Numerical methods and comparison with experiment
We present a numerical method that allows us to solve the Navier-Stokes equation with boundary conditions for the viscous flow between two concentrically rotating cylinders as an initial-value
An improved projection scheme applied to pseudospectral methods for the incompressible Navier-Stokes equations
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.
Direct simulation of a turbulent boundary layer up to Rθ = 1410
The turbulent boundary layer on a flat plate, with zero pressure gradient, is simulated numerically at four stations between Rθ = 225 and Rθ = 1410. The three-dimensional time-dependent Navier-Stokes

We investigate the dynamical and statistical features of turbulent Taylor–Couette flow (for a radius ratio 0.5) through three-dimensional direct numerical simulations (DNS) at Reynolds numbers
Assessment of direct numerical simulation data of turbulent boundary layers
Statistics obtained from seven different direct numerical simulations (DNSs) pertaining to a canonical turbulent boundary layer (TBL) under zero pressure gradient are compiled and compared. The
Turbulent Bursts in Couette-Taylor Flow.
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.
