“…Three curves on each set represent the computed values of the present study; the computed values of Summers et al (1986); and the wind-tunnel data, also reported by them. Baskaran and Stathopoulos (1989) included the standard turbulence model during the computation, whereas the computed values of Summers et al (1986) were generated without considering turbulence. The measured data are obtained from a boundary layer wind tunnel.…”

“…As shown in the figure, the solution grids are slightly different and did not exactly correspond in the two studies, but this makes little difference in these comparisons. The pertinent question of Summers et al (1986): "Whether the most obvious deficiency of the simulationits failure to reproduce the compactness of the wakecould be improved by the introduction of a more detailed treatment of turbulence," is considered in Baskaran and Stathopoulos (1989) by incorporated the well-known k-E models in the computation. The better agreement of these BASKARAN AND STATHOPOULOS…”

“…In addition, only a low rate of dissipation of turbulent kinetic energy is computed when standard k-~ turbulence models are used. To account for these effects and to improve the predictions, two simple modifications on the standard k-E turbulence models, namely streamline curvature correction (Leszchziner and Rodi 1981) and preferential dissipation correction (Gibson 1978), have been identified and applied (Baskaran and Stathopoulos 1989).…”

Advancements in computer software and hardware technology provide a new direction for analyzing engineering problems. Recently the field of wind engineering has gained significant momentum in the computer modelling process. This paper reviews the state of the art in computational wind engineering, including the finite element method, finite difference method, and control volume technique. A portion of this paper summarizes the research in this area carried out by the authors. Computations have been made for a variety of building configurations, including normal wind flow conditions for a building with different aspect ratios, and modelling wind environmental conditions around groups of buildings. The computer modelling technique may eventually enhance the design of buildings and structures against wind loading and supplement the current design practice of using building codes and standards or performing experiments in wind tunnels.

In the present study, 2-D numerical simulation of wind loads on low-rise buildings has been carried out. The simulation was carried out under FLUENT package environment in which full-scale Reynolds number, boundary layer and turbulence properties have been simulated. Wind loading effect numerically obtained on flat roof (TTU building) and pitched roof is compared with wind tunnel data. It was found that there is fair agreement between the numerical predictions and measurements for time-averaged wind loads on buildings. The computed pressure coefficients have been validated with wind tunnel TTU building model results on 1:100 scale within an average error of 20%. The effect of roof pitch for 10°, 20° & 30° on pressure coefficients for gable roof has also been investigated and the results were compared with the available wind tunnel results for 15°, 26° & 35° roof pitch. The present study shows that the numerical simulation of wind loads hold a great potential for extending codes of practice for wind loads.
