Abstract
Global demand for energy continues to increase rapidly, due to economic and population growth, especially for increasing market economies. These lead to challenges and worries about energy security that can increase as more users need more energy resources. Also, higher consumption of fossil fuels leads to more greenhouse gas emissions, which contribute to global warming. Moreover, there are still more people without access to electricity. Several studies have reported that one of the rapidly developing source of power is wind energy and with declining costs due to technology and manufacturing advancements and concerns over energy security and environmental issues, the trend is predicted to continue. As a result, tools and methods to simulate and optimize wind energy technologies must also continue to advance. This paper reviews the most recently published works in Computational Fluid Dynamic (CFD) simulations of micro to small wind turbines, building integrated with wind turbines, and wind turbines installed in wind farms. In addition, the existing limitations and complications included with the wind energy system modelling were examined and issues that needs further work are highlighted. This study investigated the current development of CFD modelling of wind energy systems. Studies on aerodynamic interaction among the atmospheric boundary layer or wind farm terrain and the turbine rotor and their wakes were investigated. Furthermore, CFD combined with other tools such as blade element momentum were examined.

Over the last decade, the production of renewable energy has rapidly increased and this development is expected to continue
To respond to the challenges associated with the modelling of wind turbines in various scales, this study will review the state of the art and most recent literature (2010–2018) on the Computational Fluid Dynamic (CFD) modelling of wind turbine energy systems
Different types of wind turbine categories will be investigated: micro this study will review the state of the art and most recent literature (2010–2018) on the CFD modelling of wind turbine energy systems
Summary
The production of renewable energy has rapidly increased and this development is expected to continue. Researchers continue to develop and optimise wind turbines to eliminate the drawbacks associated with these devices. The with highly of complex orography its represents performance using challenge simplifieddue and to linear installation wind turbines in and, complex terrainpredicting landscapes a major the models may not be adequate or accurate enough. The installation of wind turbines in complex terrain terrain combination of uncertain wind resources and the flow accelerations from the surrounding landscapes represents majorturbines challenge[3]. Another example is the installation of resources wind turbines in flow accelerations from the surrounding terrain and wake effects from other turbines [3].
