Direct numerical simulation of dynamo transition for nonhelical MHD
(2010)Pseudospectral Direct Numerical Simulation (DNS) has been performed to simulate dynamo transition for nonhelical magnetohydrodynamics turbulence. The numerical results are compared with a recent low-dimensional model [Verma ... -
Direct numerical simulation of particle-laden turbulent channel flows with two- and four-way coupling effects: Budgets of Reynolds stress and streamwise enstrophy
(2016)The budgets of the Reynolds stress and streamwise enstrophy are evaluated through direct numerical simulations for the turbulent particle-laden flow in a vertical channel with momentum exchange between the two phases. The ... -
Direct numerical simulation of particle-laden turbulent channel flows with two- and four-way coupling effects: Models of terms in the Reynolds stress budgets
(2017)In the first part of this study (Dritselis 2016 Fluid Dyn. Res. 48 015507), the Reynolds stress budgets were evaluated through point-particle direct numerical simulations (pp-DNSs) for the particle-laden turbulent flow in ... -
Numerical study of educed coherent structures in the near-wall region of a particle-laden channel flow
(2008)The interaction of small heavy solid particles with turbulence near the wall of a vertical downward channel flow is investigated by using direct numerical simulation (DNS) and Lagrangian particle tracking. The interest is ... -
Recurrence quantification analysis of MHD turbulent channel flow
(2019)We present Recurrence Plots (RPs) and Recurrence Quantification Analysis (RQA) of time series of velocities in a low-Reynolds-number magnetohydrodynamic turbulent channel flow. The flow was simulated using a fully spectral ... -
Spatiotemporal Time Series Analysis Methods for the Study of Turbulent Magnetohydrodynamic Channel Flows
(2015)In the present study, the direct numerical simulation of the turbulent flow of an electrically conductive fluid in a channel is performed and time series are recorded at a range of locations along the y-direction between ...
