Abstract
:
This paper presents a series of experimental investigations on low head sluice gate models considering the simultaneous underflow-overflow and underflow or overflow alone. The dynamic behaviour of the gates was studied in terms of pressure and gross force fluctuations on gate bottom or top for both vibrating and stationary gates. Spectrum analysis of force fluctuations was also made to identify the existence of resonance by comparing the natural frequency of the gate with the dominant frequency of force fluctuations. Analysis of the results revealed that pressure and force fluctuation coefficients are considerably higher for the simultaneous conditions of underflow-overflow, both on the gate bottom and top due to coupling effects and the coefficients are larger for vibrating gate than those of stationary one due to interaction of flow with gate movement. The effect of coupling or interaction seems to be further amplified due to quasi-resonance.
