Design of an Ornamental Bladeless Vortex Generator

摘要

Renewable energy is more relevant now than before as battery technology is advancing and as the society pursues a cleaner form of generating electricity. One of the many ways to harness energy is through wind power. Without a doubt, wind power is among the frequently used renewable energy, but traditional wind turbines have inherent disadvantages in terms of noise pollution and the danger it poses to the flying creatures. The purpose of this study is to develop a bladeless wind generator. Instead of rotational motion to harness energy, the bladeless wind generator used the concept of vortex shedding which was translated to pendulum motion. A total of three of prototypes are integrated and tested with its functionality at different wind speeds. The monitoring and gathering of data were done automatically through a data logger. The output characteristics of the prototype is then recorded and interpreted with various analysis. The results showed that the developed prototype was able to generate an average output voltage of 2.36 V in a controlled environment while when deployed in an uncontrolled environment, it was just able to generate an average voltage of 0.67 V. The prototype gave an average noise level of 63.87 dB which satisfy the noise limit required in IEC 60034-9. It was observed that the values showed high dependence on the wind speed of the environment.
