Rotor Size Optimisation of a Counter Rotating Dual Rotor (original) (raw)
Absztrakt The customers growing demand for energy utilization and the need for green and sustainable energy have changed our energy security. Changes in the energy mix have become necessary by the developments and improvements of the energy producers and the need by the population for an energyefficient and sustainable future, thus today’s expectation in this engineering field is to design more efficiently and sustainably than ever before in an economically efficient way. In our article, we are reviewing the conventional and the newly spreading non-conventional wind turbines and they place of use. After this overview, we are presenting the foundation of wind turbines efficiency and its power coefficient. Later, we are introducing a Computational Fluid Dynamics (CFD) simulation for a CounterRotating Dual-Rotor Wind Turbine (CODRWT) with different rotor sizes. After the simulation, we are examining the overall power coefficient of turbines and its change by the turbine size. Energiabi...
