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 ...
Computational fluid dynamics (CFD) Simulations of aerosol deposition in the lungs
(TSFP-9, 2015)
In the current study, Large Eddy Simulations (LES) are used to investigate the transport and deposition of inhaled aerosol particles (dp = 0.1, 0.5, 1, 2.5, 5, 10 μm) in a realistic geometry of the human airways under ...
Solution of viscoplastic flows with the finite volume / multigrid method
(National Technical University of Athens, 2013)
We investigate the performance of the finite volume method in solving viscoplastic flows. The square lid-driven cavity flow of a Bingham plastic is chosen as the test case and the constitutive equation is regularised as ...
