Developing a model for Urban Environment based on transient RANS approach

The ambient air temperature in a city is a critical parameter for thermal comfort. It also strongly
influences energy needs for cooling and heating. Thermal and radiative parameters of these surfaces can
affect urban ambient air temperature and street canyon temperature. So, using specially designed pavements
on buildings and surfaces on the streets can be an effective way to control the local urban environment. The
aim of this paper is to describe the developed model, suitable to use in urban thermal studies, and to show
the accuracy of the result by comparing them to real data that have been published from data gathering
campaigns. Also, results are compared with other models to measure the accuracy of this model against
others. Finite Volume solver in ANSYS/FLUENT 22. software is used to solve unsteady Reynolds
Averaged Navier Stokes (URANS) equations.
