Research on CFD calculation of traction ventilation system for plateau locomotives
Taking a certain type of plateau locomotive as an example,we calculated and optimized its air duct with FLUENT simulation software under plain working conditions to ensure that all parts of the air duct can meet the working requirements.Due to the low air pressure and low air density in high-altitude areas,in order to further calculate its working state in high-altitude areas,we analyzed the impact on fans and changes in ventilation efficiency under high-altitude conditions,made high-altitude corrections to each part,and selected altitude of 2800 m,4000 m and 5100 m for calculation.The calculated results were compared with those in plain areas to verify whether the ventilation system can work normally in high-altitude areas.
