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

The performances of ventilation in the buildings with quadrate and cylindrical cross-sections are compared numerically. incoming jet unsheltered-building is more horizontal comparison to unsheltered-building. dimensionless volume flow rates unsheltered-buildings respectively 0.503 0.553. sheltered-buildings flows floors immediately. velocity near floor sheltered-building greater than that sheltered-building. 0.130 0.210.Comparing buildings, unsheltered sheltered increased by 10% 61%.
