Abstract:  Based on Fluent soft platform, trairrinduced airflow of Wuhan railway station was simulated by computational fluid dynamics method. Corfiguration of trairrinduced airflow at different positions of the train was illustrated,and the distribution characteristics of trairrinduce airflow had been obtained.  With criteria in some references, safe distance on the platform had been suggested. At last, the wind load according to the trairrinduced airflow on the structure was analyzed.
Keywords:  numerical simulation; train-induce airflow; moving mesh; safe distance
