Direct Numerical Simulation and Visualization of Biswirling Jets
Advances in Mechanical Engineering, 2014 Two parallel swirling/rotating jets with a distance between them are termed biswirling jets here, which have important and complicated vortex structures different from the single swirling jet due to the negligible vortex-vortex interactions.

Direct numerical simulation of intermittent turbulence under stably stratified conditions [PDF]
Nonlinear Processes in Geophysics, 2015 In this paper, we simulate intermittent turbulence (also known as bursting events) in stably stratified open-channel flows using direct numerical simulation. Clear signatures of this intriguing phenomenon are observed for a range of stabilities. However,

Deterministic numerical solutions of the Boltzmann equation using the fast spectral method [PDF]
, 2013 The Boltzmann equation describes the dynamics of rarefied gas flows, but the multidimensional nature of its collision operator poses a real challenge for its numerical solution. In this paper, the fast spectral method [36], originally developed by Mouhot

Direct numerical simulation of matrix diffusion across fracture/matrix interface
Water Science and Engineering, 2013 Accurate descriptions of matrix diffusion across the fracture/matrix interface are critical to assessing contaminant migration in fractured media. The classical transfer probability method is only applicable for relatively large diffusion coefficients ...

Direct numerical simulation of turbulent flow above zigzag riblets
AIP Advances, 2018 We investigate the drag-reducing performance of a zigzag riblet inspired by the “Miura fold” and its influence on the streamwise vortices above a wall-bounded turbulent flow through direct numerical simulations of channel flows. The employed channel wall
