Summary

Airflow in subway systems is usually predicted by microscopic models based on the assumption that airflow is one dimensional. Three dimensional models require heavy computational loads. A practical solution is to apply a microscopic model to the target space and a macroscopic model to the surrounding space. In this paper, a two-way model is developed. There is little difference in the results between the one-way and two-way models. With the exception of the case where the structure of a station causes high airflow impedance, it is convenient to apply the one-way model to ordinary types of subway stations concerning computational load.
