Fluid Flow and Solid/Fluid Suspensions Flow in 3-D Packed Beds of Spheres: the ...
Serrenho, Ana; Miguel, Antonio FA 3-D numerical study is performed to investigate the effects of periodicity (geometry) on flow of fluid and on flow of solid/fluid suspensions in packing arrangements of fixed beds of spheres. The porosity is fixed at 0.58 and the following packing arrangements are studied: simple cubic, face-centered cubic, hexagonal, rhomboedric hexagonal and tetragonal. Simulations are carried out at Reynolds numbers rangin...
Airborne Pathogens Transport in an Aircraft Cabin
Acikgoz, MB; Akay, B; Miguel, Antonio F; Aydin, MAirborne pathogens can spread within an aircraft cabin from sneezing, coughing or breathing of a sick passenger. This paper reports a 3D numerical study on the transport of airborne pathogens inside Boeing 767 cabin. After cough or sneeze of an infected passenger, the entire unsteady pathogen dispersion process is simulated. Effects under study include the direction of coughing on the pathogens propagation and ...
