Project description.
The project of a smart city is a complex task which involves modern engineering and architectural skills.

The design of buldings is developed in synergy with the information technology, with the goal of having a selfconsistently connected urban area.

Variables like the concentration of pollution in different parts of the city, are monitored.

As an example, the evolution of the pollution in the streets and near the buildings should be predicted, in order to properly organize the traffic conditions in advance.

In order to understand and control variables like the concentration of pollution, it is important to adopt models where the nonlinear dynamics of the wind in the city is properly considered.

Near a building, the wind can change direction and speed. Vortices are generated, whose nonlinear interaction creates turbulence.

Moreover, the turbulent tail of each single building can interact, increasing the transport in the direction normal to the wind original velocity direction.

Comprehensive numerical simulations can be performed nowadays, with supercomputers allowing to properly include the turbulence dynamics.

At the same time, the computations should be sufficiently fast, to provide predictions for the variations of these variables right after a change in the input conditions.

The main task of this project is the study of the propagation of pollution, as transported by the wind.

This is linked to the formation of macroscopic vortices, depending on the wind speed and the building shape and size.

Different physical models can be used, like Reynolds-averaged Navier-Stokes (RANS) models, faster and less accurate, or Large Eddy Simulations (LES), slower but more accurate, etc.

High-fidelity simulations are going to be performed and investigated. The pollution is followed by means of markers, and the interaction of different buildings is studied.

The goal in a nutshell. The ultimate goal is to have models providing accurate predictions for the evolution of variables such as the concentration of pollution in different parts of the city (e.g. pollution due to traffic), depending on the weather conditions, such as the speed and direction of the incoming wind.
