Review of wind behavior studies especially on urban environment

Wind flow modeling on urban geometry¡ such as a set of buildings¡ cities¡ towns and tall buildings are now in the spotlight. It is important to study and simulation of wind’s dynamics due to the effects of urban areas on the attitude and regime of wind and in the other hand¡ the effects of wind’s dynamics on the urban areas. In the 1950s¡ experimental studies and measurements of weather prediction were begun and developed due to computational disability of computers to improve numerical prediction of meteorological climate. In the 1960s¡ complex geometry simulations with higher precision were begun after development of Numerical Models of Primitive Equations and increase the computational ability of computers. In the 1970s¡ the Reynolds Averaged Navier- Stocks turbulence models for simulation were discussed. Then¡ in the years 1980 numerical methods for solving these equations were developed. In 1990s¡ assessment of Advanced Turbulent Models results with wind tunnel measurements was presented. In recent years presenting number of new models were done to improving prediction precision and flow dynamics of wind on buildings especially in the pedestrian level. In the present study¡ some of the shortcomings of this issue are provided. Also important and influential papers in wind flow simulation over the past 65 years were reviewed.
