Development of a Numerical-clean-room-method, which is useful to control contaminate and arrange industrial machines in clean room

提出了一种用于控制洁净室内空气流动和污染场的数值洁净室方法，并将数值模拟结果与洁净室内大量的实验数据进行了比较，提出了一种洁净室内布置工业机械的方法。该方法是一种预测洁净室和送排气管道内整体流动和扩散场的工具。该方法依赖于数值湍流模拟方法，能够预测送排气口位置、风量、压力波动、大的流动障碍物(工业机械和工人)、小的流动障碍物(格栅地板、冲压金属板和机器的不均匀)以及影响室内流场的各种因素对室内流场的影响。将该方法与本课题组开发的通风效率法相结合，对多种不同类型洁净室的污染物扩散场进行了研究。我们从这些调查中获得了许多有用的数据，我们可以证实这个模型的准确性和实用性。

A numerical-clean-room-method is developed to control air flow and contaminate field in clean room, and to arrange industrial machines in clean room.Comparing the results of numerical simulation with many experimental data in clean room, this method is developed. This method is a tool for predicting totally flow and diffusion field in clean room and supply and exhaust duct. This method is depend on numerical turbulent simulation method and have an ability to predict flow field affected by the position of supply and exhaust openings, air volume, fluctuation of pressure, large flow obstacles (industrial machines and workers), small flow obstacles (gratings floor, punching metal boards and unevenness of machines ) and every factors which effect on flow field in room. As this method is used with ventilation efficiency rate, which is developed by our research group before, contaminate diffusion field in many different type of clean room is investigated. We have many useful data from these investigations and we can confirm the accuracy and the usefulness of this model.
