摘要
为分析及计算七氟丙烷在管道中的流动阻力损失 ,在试验研究的基础上 ,采用计算流体力学软件 FL UENT进行模拟计算 ,并与试验数据相比较 ,得出在七氟丙烷灭火系统管路流动特性研究中 ,采用计算机模拟计算替代昂贵的试验是可行的。
In order to analyze and calculate the pressure loss of HFC-227ea in piping, much experiment has been done and hydrodynamics analysis software FLUENT has been applied in simulation calculation. Comparing the experiment with computer simulation calculation, we can get the conclusion that computer simulation calculation is an effective method in pressure loss calculation, and it can substitute the expensive experiment to reduce the research cost.
