Abstract
In recent years, high speed railway trains are a main part of modern transportation which brings extremely convenient. In this case, studies on aerodynamic performances and phenomenon of trains are the core for further development of high-speed trains. With this in mind, this paper briefly introduced aerodynamic formulae as well as summarized some major computational designs of train noses, with the corresponding experimental results of some designs. On this basis, the application of some designs was explained, with follow up limitations and outlooks of aerodynamics of high-speed trains. According to the analysis, results show that designs in China focus more on reducing aerodynamic drag, while the flatter design in Japan has a better overall aerodynamic performance. In addition, the limitations of current facilities as well as the prospects for the high-speed railway systems are demonstrated. Overall, these results shed light on guiding further exploration of high speed railway development.
