Analysis and Field Study of INVELOX Wind Turbine

INVELOX wind turbine is a new concept in harnessing wind energy. This technology gathers wind by omnidirectional or unidirectional intakes and increases wind velocity by concentrating wind in the venturi section. Then return it back to the environment through the diffuser. INVELOX technology offers suitable financial indicators and solves windmills environmental issues, like noise. Therefore, INVELOX becomes an opponent of fossil fuels. This technology uses 84% smaller blade compare to windmills, so it overcomes installation difficulties and it is an economically feasible system in wind energy industries.
In this paper, CFD simulations are used to evaluatethe speed ratio of 1.7 of the system and field data of a small scale INVELOX, installed in Siahpoush, Manjil was reported. In order to evaluat duct effects on the turbine performance, INVELOX turbine was compared to the traditional wind turbine with the same blade diameter. So output power and energy were recorded for both turbines. This study shows INVELOX has the ability to harness, deliver and accelerate free wind and produces more power and energy with a higher performance.
