Research On Wing-Solar Tower-Style Generation Device And Its Methodology

In the modern society with all the environment problems such as shortage of energy, atmosphere pollution, water deterioration and mineral deposit depletion, it is becoming more and more widely acknowledged by countries all over the world, that the electrical power generation from renewable energy plays a critical role. The definition of renewable energy refers to energy "clean" and creates little pollution, examples including wind, solar, biomass, tidal and geothermal energy. The wind-powered generation is a typical application, which utilizes the wind’s power in nature coming from climate change, in order to generate electrical power for mankind’s benefit.This paper would make a summary on wind-solar generation technology, starting from the background and importance of the research, discussing about the worldwide research status in this area, showing the bottleneck of current research, as well as describing the research goal of this project. Aimed at the weakness point of current wind-solar power utilization and fan blade manufacturing, this paper states a kind of new tower-style generator which captures wind power more efficiently with micro-fan blade. The author has modeled a single-layer-8-channel system based on the block diagram and comparison of multiple channels. The Hydrodynamic calculation software FLUENT is employed here for numerical simulation and optimization. The author also uses the simulation result for further analysis and gets the wind power generation efficiency. Finally, an experimental platform is manufactured based on the size of the model. The paper also discusses wind-power storage technology because of the unstable nature of the power.In this paper, the system utilizes wind and solar power for generation. According to the generation theory, in order to increase the outlet velocity of the wind channel, the inner side of the channel will be built with heat-absorbing material; based on the design of inlet and outlet port of the air channel, together with other related parameters and sizes, we used3D software UG for modeling, ICEM CFD for mesh division, FLUENT for numerical simulation, and all these results for parameter calculation of the fan blade. During the experiment, we built the model, selected the appropriate environment for test, measured all necessary parameters with our model, and then calculated the centrifugal force, air pressure and the aerodynamic torque of the fan blade. But the experimental results showed that big error exists between simulation and field test, the reasons lie in impeller blade, spindle, generator and the ideal software simulation etc.The author made a high-level usage of large CFD numerical simulation software in the research of this system. Numerous human power and funds were saved by this. Moreover, it did not achieve ideal results, but the novel system stated here takes much less land area than traditional ones, as well as further research expense. As a result, it would improve the R&D level of small size wind-solar generation device in China, and put a solid ground and support for further research on this type of device in the future.
