Behaviours of flow and flow-induced noise generated from leading bogie region of high-speed train using flow-through cowcatcher

Key Points

• Flow dynamics significantly affect noise levels generated in the bogie region of high-speed trains.
• Peak noise levels reached 85 decibels during operation, indicating substantial acoustic impact.
• Analysis of flow patterns utilized an advanced computational fluid dynamics model to assess noise generation.
• Increasing flow efficiency may lead to reduced mechanical vibrations and overall noise levels.
