Numerical research on cross-ventilation flow of a generic building in unsheltered and sheltered conditions: impact of cross-section [PDF]

open access: yesE3S Web of Conferences, 2022
The performances of ventilation in the buildings with quadrate and cylindrical cross-sections are compared numerically. The incoming jet in the cylindrical unsheltered-building is more horizontal in comparison to the quadrate unsheltered-building.
