The Effect Of Building Shape Modification On Wind Pressure Differences For Cross-Ventilation Of A Low-Rise Building

The present study investigates the effect of alteration in the building shape due to some common remodelling practice on the wind pressure differences Δp for cross-ventilation of a semi-detached low-rise building using Computational Fluid Dynamics (CFD). A commercial code ANSYS CFX was employed to s...
