Study of invelox wind turbine considering atmospheric boundary layer: Based on numerical simulation

Abstract

The flow field characteristics of increased velocity (Invelox) system under different wind direction were studied by computational dynamic fluid (CFD) method. Since the Invelox wind turbine system needs to be placed in external space to operate, the atmospheric boundary layer (ABL) wind profile must be considered. The Invelox system was simulated with uniform velocity inlet and exponential wind profile inlet. The results show that when the wind direction is more than 90 degrees from the axis of the venturi pipe, the power generation efficiency of the system will decrease sharply. When the Angle exceeds 120 degrees, the system does not generate electricity. After considering ABL, the speed ratio (SR) of the system will decrease.
