In recent decades, the Automotive sector and, in particular, that of Motorsport has seen an increasing importance of aerodynamics in the development of racing and non-racing cars. The technology has made it possible to "predict" flow behaviour through the use of CFD simulations and to develop innovative methods to make the most of air energy. Aerodynamics allows to improve the performance in the field of vehicle dynamics, along with thermal management and overall efficiency. Although computational fluid dynamics has come a long way and, the accuracy of simulations has increased considerably, it is still necessary to carry out track and wind tunnel tests in order to validate the numerical results or to investigate those that are still uncertain areas. In this project, a study was carried out on the availability of cheap and disposable pressure sensors suitable for measuring the flow rate from the radiators of an F1 car. The sensors have also been tested in the wind tunnel combined with a pressure probe. Compared to a Pitot tube, the theoretical advantages of a Kiel probe for this particular purpose, have been verified both numerically and through wind tunnel tests.
