Design and Simulation of a Test Bench for Horizontal Axis Wind Turbines

Currently, the global energy matrix is governed by the generation of energy with non-renewable resources. The downside of these resources is that they take several thousand years to form and cannot be replaced as quickly as they are used today. Peru, due to its strategic location, is a country with great wind potential. However, it is not used enough due to the lack of laboratory equipment that studies this form of energy generation. The present work consists of the design of a test bench for horizontal axis wind turbines that contains an open circuit wind tunnel to generate a uniform wind flow towards the turbine blades. There are fan blades attached to the shaft of a motor, which generate wind inside the tunnel. This tunnel has a nozzle to stabilize the flow and said basin tunnel with the capacity to generate a wind of up to 16 m/s with a 25 HP motor. There is a logic controller that allows 2 types of operation as required by the user. The following article mainly contains the mechanical design of the structure and geometry of the tunnel, a numerical simulation of the fluid inside the wind tunnel, a simulation of stresses in the structure, and a simulation of the controller for the 2 types of operation.
