actual discharge coefficient的用法和样例：
- Improvement of the orifice discharge coefficient may not result in stability improvement as illustrated in one test series.
- The utilization of CFD numerical simulation in standard orifice flow meter provides a new method on the estimation and optimization of discharge coefficient.
- The effect of Reynolds number and mass floe ratio on the discharge coefficient and pressure distribution for the flow in channel with rib turbulators and double-row bleed holes are investigated.
- Correlations between jet Reynolds number and discharge coefficient, and between inlet crossflow velocity ratio and discharge coefficient were obtained based on the experimental data.
