Uniform Air Supply System Adjusted by Perforated Plate

Based on the analysis of uniform air supply system theory of duct with constant section combined with the characteristics of train environment, uniform air supply system adjusted by perforated plate is put forward, and theoretical calculation, CFD simulation and experimental tests are carried out. The result shows this air supply system can be completely designed by theoretical calculation, and has significant advantages in its convenient adjustment, low pressure drop, low energy consumption and noise.
