چکیده
|
The ocean has provided a new avenue in the quest for renewable energy. one potential source of energy is marine current, which is harnessed using either vertical or horizontal axis turbines. this paper describes a particular type of vertical axis turbine which is suitable for low current velocity applications. the simulation of savonius-type turbine, which hitherto has never been proposed for marine current energy application, is presented in this paper. a 3d computational model was built and analyzed using a computational fluid dynamic analysis using proprietary software. the overlap ratio is identified as one of the important factors in savonius turbine performance. this paper provides results of the investigation for a range of overlap ratios between 0.1 and 0.6 and it was found that the maximum torque can be obtained at overlap ratio of 0.21.
