Abstract:In this paper describes the design and fabrication of a wave flume and associated equipment. The water wave generation by a triangle wedge is examined in this paper. Wave flume is fabricated by a concrete flume which is 0.75-meter-wide, 1.3-meter-tall and 11 meters long. One side of the flume is made of concrete and the other side is made of clear mica sheets for observe the water wave profile. Wave flume is equipped with a triangle wedge which located at one end of the wave flume, and this triangle wedge can … Show more
“…10 and 11 that increase in operating frequency of the wave generating mechanism results in higher wave height and reduction in the wave time period. Observations for variation in the wave height and time period are in consonance with the findings reported in the literature [65][66]. During the energy storage mode, wave vertical force is utilized and the wave energy is converted to strain energy of the spiral spring in the ESE.…”
In this work, a novel design of an oscillating body-type Wave Energy Converter (WEC) is proposed with an efficiency of 48.73 %. Innovative features of the new design include the integration of Mechanical Motion Rectifier (MMR), Motion Regulator (MR), Energy Storage Element (ESE), and Electric Generator (EG) with the operation controlled by a microcontroller, limit switches, and linear actuator. Lab experiments conducted with a prototype ensured a peak voltage of 8.1 V and peak power of 4.3 W. Experimental and MATLAB theoretical simulation results demonstrated the average power of 55.2-148.3 mW for a wave height of 50-125 mm. In comparison to the conventional operation, where the electric generator is directly driven by wave motion, the proposed design will ensure higher peak power and better energy utilization characteristics of the generated voltage waveform. Simulation results are presented with the incorporation of non-circular gears that ensure modification of the voltage waveform for better energy utilization.
