| 中文摘要: |
| 通过对三氟甲烷灭火剂在管网中的流动状态、管网中灭火剂流动的压力~时间(p~t)曲线分析,进一步阐明三氟甲烷灭火剂气液两相流动状态下管道压力损失,利用推导的压力损失计算公式对具体的系统进行实际计算,并通过实际的系统喷放所测得的数据对计算结果进行验证,进一步证明推导的压力损失计算公式的可用性和对三氟甲烷灭火剂在管网中的流动状态分析的正确性。 |
| 英文摘要: |
| This paper analyses the flow state and the pressure curve (vs. time) of HFC-23 extinguishing agent in pipeline, whereby the pressure loss of HFC-23 extinguishing agent in two-phase (i.e. gas and liquid) condition is illustrated. By comparing the calculation result and practical test data, the accuracy of the pressure loss formula is verified and the analysis of flow state of HFC-23 Extinguishing Agent in pipeline is further testified. |
