| Abstract: | The mastery of the velocity distribution of a push-pull airflow is the base for the push-pull ventilation system design. In this paper, the velocity distribution is investigated both theoretically and experimentally. The velocity distribution in a now field and the limited velocity position being important for the push-pull ventilation system design are established by numerical computation. We established the limited velocity position, which is of practical importance for push-pull ventitation systems design. The results of calculation are in good agreement with experimental values. |
