Critical Sources of Aerodynamic Resistance in a Medium Distance Urban Train: a CFD approach

In this article, the aerodynamic behavior of a commuter train operating at average speeds is evaluated, by means of computational fluid dynamics; the main goal is to identify the main aerodynamic drag sources. The study consist of two phases; the first one is the aerodynamic analysis of the current...
