本文介绍了计算流体动力学（CFD）建模的结果 用于评估脉冲气体平衡的水循环模式 Reservoir，位于加利福尼亚旧金山。CFD建模用于开发和测试 通过减少储液罐进口/出口流量来评估储液罐的改进 不希望出现的流动特征，如内部死点的短路和再循环 水库。首先，对CFD建模和中国的水质问题进行了一般性讨论 介绍了水库的配水情况。然后是背景和基本知识 给出了有关水库的信息。之后，各种场景的流模式 利用CFD模型对其进行了评估，并给出了结果。包括数字。

This paper presents the results of computational fluid dynamics (CFD) modeling that were used to evaluate the water circulation patterns of the Pulgas Balancing Reservoir, located in San Francisco, California. CFD modeling was used to develop and evaluate reservoir inlet/outlet modifications and to optimize flow patterns by reducing undesirable flow features such as short circuiting and recirculation in dead spots within the reservoir. First, a general discussion of CFD modeling and water quality issues in water distribution storage reservoirs is presented. Then background and basic information on the reservoir is given. After that, the flow patterns for various scenarios are evaluated using CFD modeling and results are given. Includes figures.
