对于特殊的隔离场所,如事故状态下的控制室等,需要严格控制外界环境的污染气体进入到室内环境中,而开关门过程会引起外界气体的内侵入。本文中,建立了内套间和外套间的模型,利用动网格技术,研究平开门的开关门内侵入过程。并在外套间设置了SF_6作为示踪气体,监视内侵入流量,并计算了内侵入量。结果发现,前门面的牵引和挤压作用引起了内侵入气流。对于不同的旋转用时,内侵入量保持在0.60 m~3/h。
For special isolation places, such as the control room in the event of an accident, it is necessary to strictly control the polluted gas of the external environment into the indoor environment, and the process of opening and closing the door causes the internal gas intrusion into the environment. In this paper, the model of the inter-suite and the inter-coat is established, and the moving grid technology is used to study the intrusion process of the open-door. In addition, SF_6 was set as a tracer gas in the coat to monitor the invaded flow and calculate the internal invasion. It was found that the traction and extrusion of the front facade caused the inward invasion of the airflow. For different rotation time, the amount of intrusion remained at 0.60 m ~ 3 / h.
