MHD flow past a circular cylinder using the immersed boundary method
(2010)
The immersed boundary method (IB hereafter) is an efficient numerical methodology for treating purely hydrodynamic flows in geometrically complicated flow-domains. Recently Grigoriadis et als. [1] proposed an extension of ...
Numerical simulations of turbulent flow in an eccentric annulus of unit eccentricity
(TSFP-9, 2015)
In this study, we perform Direct Numerical Simulations (DNS) of fully developed turbulent flows in eccentric annuli having different diameter ratios. Annuli of unit eccentricity, and diameter ratios of 0.2591 and 0.1395 ...
Effect of turbulent pulsating flow around a near-wall submerged cylinder on the potential motion of bed and suspended loads
(International Society of Offshore and Polar Engineers, 2016)
In the present work, the pulsating flow around a submerged cylinder close to the impermeable seabed is examined by means of Large Eddy Simulations (LES). A Reynolds number equal to Re = 5000 is considered, based on the ...
Large Eddy Simulation of near-bed pipelines in oscillatory flow
(2018)
A series of unsteady, three-dimensional numerical simulations of the incompressible, oscillatory flow around a near-bed pipeline is presented. A flow at Reynolds number equal to Reαo=20,000 with respect to the oscillatory ...
The ASBM-SA turbulence closure: Taking advantage of structure-based modeling in current engineering CFD codes
(2015)
Structure-based turbulence models (SBM) carry information about the turbulence structure that is needed for the prediction of complex non-equilibrium flows. SBM have been successfully used to predict a number of canonical ...
The contribution of active and inactive structures to the statistics of a turbulent pipe flow
(2017)
The current study is a short follow-up to our most recent work (Stylianou et al., 2016), where among other things we have presented an effective criterion suitable for distinguishing large-scale coherent structures with ...
Direct numerical simulation of particle laden flow in a human airway bifurcation model
(2016)
During the delivery of inhaled medicines, and depending on the size distribution of the particles in the formulation, airway bifurcations are areas of preferential deposition. Previous studies of laminar flow through airway ...
