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

Abstract

In this study, a microclimate analysis has been carried out starting with a partic-ular urban configuration, "the street canyon". The analysis, conducted by per-forming 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 3-D characteristics of the flow field on the heat transfer coefficient, has been carried out. The check of the urban mi-croclimate through this type of study, can be helpful to find solutions at thermal comfort and energy saving.
