In this study, wind data from Isfahan Meteorological Station in the mean warmest day (30 July) and coldest day (30 January) of the year 1396 for CFD studies on wind distribution in three urban configurations (traditional, raster and high-resolution discrete). ) At the local scale that represent the general shape of the morphology of Isfahan city species, CFD numerical simulations were performed in Envi-met and Design Builder software to visualize the wind energy result of each urban texture. Finally, three different urban contexts were compared and analyzed with several parameters related to urban morphology and wind environment. The simulation results show that: 1) traditional textures based on numerical max wind velocity and direction of the software on the warmest day equal to 26.26 and the coldest day equal to 2.68 m / s as well as general analysis on geometry The texture obtained from the influential morphological indices showed that the traditional texture was completely designed on the basis of stability. Textural morphology indices have shown that urban planners and tenants can optimize energy consumption and the efficient utilization of urban wind streams by applying urban morphology principles. 2) Maximum numerical results of wind velocity and direction in raster texture on the warmest day 2.73 and the coldest day 2.80 m / s and the high-discrete peak on the warmest day 4.26 and the coldest day 4.08 m / s, respectively. Clay on the geometry of the two new textures showed that modern urbanism has grown less well-adapted to the natural environment, including climatic conditions and indigenous culture. 3) The large differences between different characteristics of urban morphology and the different impacts of wind energy flows in the three different contexts indicate the significant impact of urban morphology on potential wind currents, also through analysis we found that urban morphological indices correlate with the potential index of wind currents. Significantly, and with the help of these morphological indices, we can accurately and easily compare the output of wind energy flows across different urban contexts with respect to an efficient energy approach, 4) Finally the study results can be used as A Practical Guide for Evaluating the Impacts of Urban Wind Flows and their Interactions On urban morphology also the proposed methods in this study can be used as a maximum analysis for applied measures to reduce the negative effects of wind flow on urban management in Isfahan.
