Abstract

human used shelterbelts as techniques to improve climatic condition and there have been done studies more than earlier to find the best way to reduce strong winds effects in a logical wayWindbreaks present a resistance to the approaching airflow, forcing the air to flow at a reduced speed while accelerating it over the top, providing shelter near the ground for some distance leeward of the windbreak. Windbreaks are artificial or natural obstacles that stand against the wind and change patterns of airflow in windward and leeward side of the windbreak. The recognition of wind effects and the need for wind protection, in order to provide protection from wind to crops and livestock, store carbon, and offer habitat to numerous insects and human welfare.As we better understand their function, we will be able to utilize them more efficiently to create more stable landscapes.CFD models can be used to provide a realistic and precise wind flow simulation around structures with a specific geometry. CFD is a methodology for obtaining a discrete solution of real world fluid flow problems. Therefore, numerical simulations have been used to survey the wind flow characteristic around natural and artificial windbreaks.
