| 英文摘要: |
| Multi-Hole orifice pressure differential flowmeter has been widely used due to this ability to quickly adjust the flow field and
effectively reduce pressure loss, but it still lacks complete structural parameter design and performance optimization design criteria. In
this paper, the actual flow test of the proposed symmetric porous orifice differential pressure flowmeter is carried out, and its
measurement performance is compared with the numerical simulation results. The results show that the symmetric porous orifice
differential pressure flowmeter can effectively improve the measurement accuracy ( ± 0. 5%), reduce pressure loss, have better
adaptability. Test results are consistent with numerical simulation results, verify the correctness of numerical simulation and calibrate the
new flowmeter, the research results can effectively broaden the porous orifice flowmeter The scope of application. |
