Efficient treatment of complex geometries for large eddy simulations of turbulent flows
Incompressible turbulent flow over a backward facing step at Reh=5100 is investigated by large eddy simulations (LES). The ratio of the oncoming boundary layer thickness δ to the step height h was set to 1.2. Additionally ...
Computational fluid dynamics (CFD) Simulations of aerosol deposition in the lungs
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 ...
Large-eddy simulations of the turbulent Hartmann flow close to the transitional regime
A series of large-eddy simulations (LES) of turbulent and transitional channel flows of a conductive fluid under the effect of a uniform magnetic field applied in the wall-normal direction, usually referred to as Hartmann ...
Large Eddy Simulation of near-bed pipelines in oscillatory flow
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 ...
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 ...
Direct numerical simulation of particle laden flow in a human airway bifurcation model
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 ...
