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 ...
The effect of flow rate, head position, and inhaler orientation on the airflow and particle deposition in an mri-based mouth-throat geometry
(International Symposium on Turbulence and Shear Flow Phenomena, TSFP10, 2017)
The mouth-throat plays a key role in the administration of inhaled medicines. It is an area of intense filtration, where an unacceptably high fraction of the released drug dose is deposited and thus wasted. Due to the ...
Fully turbulent flow in a physiologically realistic human airway bifurcation
(TSFP-9, 2015)
Recent computational studies have shown that the airflow in the upper human airways is turbulent during much of the respiratory cycle. A feature of respiratory airflow that poses a challenge to computations based on ...
