| Abstract: |
| 【Objective】To explore the effects of flow, shrinkage ratio and sediment content on the head loss of the triangular central measuring tank.【Method】The physical tests of 6 groups of flow rate (0.031~0.093 m3/s), 3 groups of shrinkage ratio (0.375~0.625) and 5 groups of sand content (0.69~3.08 kg/m3) were carried out. The results of the physical test were analyzed by range analysis and analysis of variance. The dimensional analysis method was used to establish a prediction model of water head loss.【Result】The head loss decreases with the increase of shrinkage ratio, increases with the increase of flow rate, and increases with the increase of sediment content. The shrinkage ratio had the most significant effect on the head loss of the triangular central tank, followed by the flow rate, and the sediment content had no significant effect on the head loss. A prediction model of head loss in a triangular central sink was established. It is verified that the relative error range between the predicted value and the measured value is -4.44%~5.41%. The model can accurately predict the head loss of the triangular central measuring tank.【Conclusion】The variation law of head loss, flow rate, shrinkage ratio and sediment content of the triangular central measuring tank was obtained. The research results can predict the head loss of the triangular central volume tank with different flow rates, shrinkage ratios and sediment content within a certain range. |
