【Abstract】 According to the factor influencing air quality inside high-speed train, this article sums-up the methods to improve
the air quality. Because of the importance of air distribution, the view about numerical simulation of airflow inside high-speed train
is discussed, which specially includes questions for building the physical model, selecting the turbulence model and boundary
conditions. This article provides a guideline for future numerical simulation of airflow inside high-speed train. This article
establishes a basis for high-speed trains’ air quality improvement and assessment with CFD technology, which also provides a
guideline for future numerical simulation of airflow inside high-speed train.
