Abstract |
|
In the present study, 2-d numerical simulation of wind load on a building having differential height is carried out to understand impact of windward building geometry on overall pressure distribution on building. The simulation was carried out in ANSYS CFX package with effect of wall roughness and geometry induced turbulence. Wind loading effect numerically obtained on flat roof (TTU Building) and compared with wind tunnel data obtained by L.S. Cochran (1992) and Numerical simulation results by S. Ahmad, M. Muzzammil, and I. Zaheer. It was found fair agreement between numerical simulation carried out in CFX, wind tunnel results and Simulation done in fluent by S. Ahmad. The computed pressure coefficient is validated with wind tunnel results of TTU (Texas Tech University) building with an average error of 15%. The present study shows that pressure coefficient distribution around structure having differential height is different from single span structures and further parametric detail study must be done in 3D simulation |
