Influence of the geometrical parameters of urban canyons on the convective heat transfer coefficient

In this study, a microclimate analysis has been carried out starting with a particular urban configuration, "the street canyon". The analysis, conducted by performing numerical simulations using the finite volumes commercial code ANSYS-Fluent studies how the thermal and flow field are affected by the effect of the solar radiation, varying the ratio H/W. Furthermore, a thermo-fluid dynamic analysis of natural convection effects and of 3D characteristics of the flow field on the heat transfer coefficient, has been carried out. The check of the urban microclimate through this type of study, can be helpful to find solutions at thermal comfort and energy saving.
