The complexity of the urban environment and its undeniable connection with the energy balance equation opens the doors for researchers to understand phenomena such as the Urban Heat Island (UHI). The least studied factor of the UHI is vehicular anthropogenic heat. Using Computational Fluid Dynamics (CFD) software, the aim is to understand the thermal environment within an urban canyon, based on two variables, the heat produced by the vehicle combustion engine and the orientation of the street (North - South and East -West). The analysis of the correlation of these variables is based on the information obtained from the simulation in different height strata, considering constant values such as direct radiation, diffuse radiation, emissivity and absorptivity of materials and a fixed temperature for the bonnet or hood of the car, altering the number of automotive vehicles and the orientation to examine the different patterns of the thermal profiles. The research opens the way to understand this phenomenon and be considered in simulations for the energy efficiency of buildings, since it directly impacts the facades of buildings and the determination of passive and active cooling techniques. |
