Design And Research Of 100W H Vertical Axis Wind Turbine

Today,with the rapid development of economy,the living conditions and standards of human beings have been greatly improved,but the exploitation and utilization of earth resources are also increasing.Traditional energy such as oil,coal and natural gas are exploited and utilized in large quantities,which will undoubtedly aggravate the environmental pollution,and the traditional energy will be exhausted one day.For this reason,the country proposes to not only develop economy but also ensure environmental quality.Therefore,clean,pollution-free and renewable new energy sources,including solar energy,wind energy,marine energy,etc.,have been vigorously promoted by the country,which are all renewable new energy sources that can be reused.Because of their recyclability,they are favored by human beings.China's land area is very wide,with rich wind energy resources,suitable for the development of wind power generation.Therefore,this project designed a 100W H-type vertical axis wind turbine for wind power research.Firstly,the performance of the generator is tested.According to the relevant parameters,SolidWorks is used to carry out three-dimensional modeling,and workbench software is used to carry out simple load analysis.Finally,fluent software is used to carry out different installation angles of-8°,-3°,2°,7°,12°simulation analysis is carried out to analyze the operation status of the wind turbine at different installation angles and find out the appropriate installation angle.It provides the basis for the follow-up research of variable pitch vertical axis wind turbine.Through the numerical simulation analysis,it is found that the different installation angle of the blades and the different speed ratio of the wind turbine tip will have an impact on the wind energy utilization of the wind turbine.When the installation angle is 7°,the wind turbine has a larger torque coefficient and the overall operation state of the wind turbine is better.
