Effect of model scale and airflow velocity on aerodynamic noise prediction for high-speed train leading car and bogie

Effect of model scale and airflow velocity on aerodynamic noise prediction for high-speed train leading car and bogie

Predicting noise from the actual train model by numerical simulation and wind tunnel testing requires appropriate corrections based on reduced model scale and airflow velocity. This paper utilises the Improved Delayed Detached Eddy Simulation method (IDDES) in conjunction with the Ffowcs Williams-Ha...
