Design and research of wave-current circulating flume with push-shake combined wave making
In view of the interference between the flow making device and the wave making device in the experimental wave flume,a wave-current circulating flume with push-shake combination is developed.The design and verification are carried out from two aspects of flow making and wave making respectively.The circulation channel,flow making drive device and steady-flow outlet are designed comprehensively to ensure the stability and controllability of water flow in the experimental area;The upside-down swing structure is adopted,combined with the movement characteristics of parallelogram structure,to realize the upside-down push-swing combined wave making,so as to ensure the waveform quality and reduce the influence on the flow channel.A mathematical model is established to analyze the relationship between the push block motion and wave elements.Based on Siemens PLC,the measurement and control system of experimental test platform is developed,and the whole experimental platform ias built to complete the performance tests of the flume.The results show that the platform can realize the maximum flow velocity of 1.5 m∙s-1 alone,the period of 1-4 s,the wave height range of 0.1-0.6 m and the required wave-flow coupling,which can meet the relevant scientific and educational application requirements
