Cascade Theory for Design & Development of Darrieus Wind Turbine

Since ancient past humans have attempted to harness the wind energy through diversified means including horizontal wind turbines and vertical axis wind turbines (VAWTs). In this modern time, there is resurgence of interests in VAWTs as wide range of research is being conducted using several aerodynamic computational models. These models are crucial for deducing optimum design parameters and also for predicting the performance before manufacturing the blades of turbines. It has been found that at present some of the most widely used models are Double multiple stream tube model, Vortex model, Cascade model, etc. In this project, Cascade model is implemented for design and optimization of parameters of Darrieus wind turbine. Then, a three bladed wind turbine is proposed as candidate for further prototype testing after evaluating the effect of several parameters like turbine power, torque and efficiency.
