6.3 RECOMMENDATION AND FUTURE WORKS This thesis has many limitations that should be attended to gain better accuracy of the simulation works. In this thesis, only simulation with validation is done with the intention of doing further studies on the performance evaluation of wind turbine. This thesis is just a simple initial endeavor that is expected to contribute in the development of higher order simulations in the future. Some limitations with recommendations to attend them are mentioned here: In this project, only simulation with validation is done with the intention of doing further studies on the performance evaluation of wind turbine. It is recommended to do further studies like studying the effect of using different blade profiles, studying the effect of turbine radius and chord length etc. 2D simulations has its limitations as it doesn’t consider 3D effects like tip vortex that leads to overestimation of generated power. So, the best results are expected to obtain by developing a 3D model which is recommended to develop. The mesh and time dependent study done here needs more trial and error attempts which could not be done due to time and computational limitations but is recommended and intended to do in the future. The simulation was done on a personal computer with low computational capacity. For running this type of transient simulations, a device with better capacity would be required and recommended. This thesis has many limitations that are intended to be attended in the future endeavors. The future endeavor would include evaluating wind turbine performance parameters for example: the effect of different airfoils, the effect of chord length, the effect of turbine radius length etc. and the knowledge obtained from those simulations can help in the design optimization and improvements of H-Darrieus vertical axis wind turbines. 55 Also, to overcome the limitations of 2D model, a 3D model may be developed and used implementing higher computational power. |
