Study on under-floor flow of railway vehicle using on-track tests with a Laser Doppler Velocimetry and moving model tests with comb stagnation pressure tubes

To study airflow under moving trains, which we call an under-floor flow, we conducted on-track tests using a Laser Doppler Velocimetry (LDV). The LDV was mounted at the transverse center of a vehicle on Fastech360S which is a test vehicle for the latest Shinkansen train. With the no-contact sensor LDV,...
