説明
Trapped air in a liquid conduit has a great influence on the fluid transient. In this paper, especially its effect on the transient flow rate is studied experimentally and analytically. Transient flow velocity, following a quick opening of a valve attached at the downstream end of the test pipeline, was measured experimentally. The experiments showed that the transient flow velocity often exceeds the final steady state flow velocity. The numerical calculation by means of characteristics method showed a good agreement with the experimental results. Maximum value of the transient flow velocity depends on the volume and the position of the trapped air, and the pressure loss of the pipeline and the valve, and the pressure at the downstream side of the valve. Five dimensionless parameters, which represent above-mentioned factors respectively, are derived, and the relations between the maximum flow velocity and these five parameters are expressed graphically.
