Increase the Smart Cities Development by Using an Innovative Design for Vertical Axis Wind Turbine

In the actual urban development context, the smart city concept is frequently used.This concept has not an unique definition, but is always defined as of positive impact.At the base of this concept, is placed the challenge to reduce the environmental impact and the carbon footprint.Smart city is a system with people, financing, services, materials and also energy development.To create a sustainable smart environment is crucial to integrate different renewable energy, transport and data flows in city planning and management.However, the implementation of new technologies must be fitted with the existing structures.In this paper, we study a counter rotating vertical axis wind turbine.To investigate the flow in this new concept we used the CFD methods.For solving the Navier-Stokes system equation the commercial CFD ANSYS Fluent was used.The vorticity magnitude and the momentum and power coefficient variation by blade position resulting from the numerical simulations are presented.
