Towards realistic design of wind dams: An innovative approach to enhance wind potential

- An innovative methodology to increase the wind potential.
- Introducing new generation of wind dams and underground wind farms.
- Reducing the environmental impacts of employing conventional wind farms.
- An efficient method to employ low wind speeds.

In an attempt to discover alternative energy sources to fossil fuels which are being depleted on the increase, Renewable Energy Sources (RES) have gained considerable attention in recent years. RESs are also represented as clean sources; emitting comparatively lower Greenhouse Gases (GHGs) emissions; thus, they are climate friendly. Among RESs, wind energy is one of the most abundant and increasingly cost-competitive energy resources, and it is becoming the fastest growing source of electricity in the world. Regarding the improvement of wind power, one of the key aspects that must be considered is achieving enhanced reliability and efficiency at once. In this paper, we introduced and applied an innovative method to make wind dam which is a new approach to wind farms' site selection for production of electricity. The proposed method enhances the wind potential by means of a natural or artificial barrier such as a hill, and is supported by analytical expressions and Computational Fluid Dynamics (CFD) models. A systematic case study has been designed at a site near the city of Tehran, Iran, and an analytical method has been applied that includes meteorological data analysis, CFD modeling along with energy power and economic assessment.
