Dynamical computational fluid dynamics modeling of the stochastic wind for application of urban studies

In light of the lack of stochastic wind modeling, this study intends to introduce for the first time an approach in order to generate dynamic wind. This is followed by a brief discussion of existing approaches in urban-scale wind modeling and their major shortcomings. For this purpose, a computational Fluid dynamics (CFD) model is developed considering a novel cylindrical computational domain. An analytical and a parametric study have been also conducted to obtain suitable sizes for the domain geometries. The advantages of the proposed model comparing to the traditional approaches are depicted using a case study of array of cuboids.
