Performance Improvement of Modified Omnidirectional Ducted Wind Mill

Multi physics simulation has progressed significantly in the recent years so that predictions of flow around and inside complex geometries are now possible. In the present work, simulations are used to evaluate a highly acclaimed innovative wind power generation system known as omnidirectional wind turbine. The model was developed using ANSYS 16. The fluid dynamic modules were employed. The objective was to validate that this patented technology significantly outperforms traditional wind turbines and it delivers superior power output. A full scale model is built to verify laboratory and field test data and to utilize the validated model as an effective design tool during product development period. The computations involved cases with different incoming wind directions and changes in the intake geometry. The results are compared with those obtained by using another CFD package. The results illustrate capturing, accelerating and concentrating wind. Increased wind velocities result in significant improvement in the power output. Here, grid independency test is also done.
