Wind turbine, computational fluid dynamics, guide vaneAbstract
The need for energy gives rise to various innovations and developments in the manufacture of power plants. Technological developments have also resulted in the depletion of fossil energy. A wind turbine is a wind-powered power plant that produces electricity. A wind turbine with a vertical axis in the form of awind turbine crossflow has many advantages, including the turbine can rotate at low speed and is relatively suitable for use in Indonesia. The addition of a guide vane can improve turbine performance by looking at the difference in air flow that occurs when compared to a wind turbine without a guide vane. The air flow can be seen by performingsimulations computational fluid dynamics. This research was designed with several methods such as the literature study method for initial learning and understanding by collecting various journals, the simulation method for the research process which is divided into pre-processing, processing and post-processing, as for descriptive methods to describe the results obtained so that conclusions can be drawn. The results obtained in the form of velocity contours and pressure contours so that you can see the air flow that a wind turbine with the addition of a guide vane circularis better because the air flow is compressed so that it has a greater thrust, and the pressure difference that occurs causes the value of the drag force to be greater than lift force so that the wind turbine can rotate. The difference in wind turbines with the addition of a guide vane circularalso results in the formation of vortexes.References
