2.3 Aerofoil
Aerofoil is the cross-sectional of an object that are moved through a fluid such as air, and aerodynamics force created. Aerofoils are employed on aircraft as wings so then it will produce lift or others depending to the blade shape to produce thrust. The two of these forces are perpendicular to the air flow. Drag is a consequence of the production of lift/thrust and acts parallel to the airflow. Other aerofoil surface includes tail-planes, fins, winglets, and helicopter rotor blades. Control surfaces (e.g. ailerons, elevators and rudders) are shaped to contribute to the overall aerofoil section of the wing or empennage (Skybrary, 2011).

As the cooling infrastructure of server rooms has increased in complexity, CFD has also become a useful tool in the data center for analyzing thermal properties and modelling air flow. CFD software requires information about the size, content and layout of the data center. It uses this information to create a 3D mathematical model on a grid that can be rotated and viewed from different angles. CFD modelling can help an administrator identify hot spots and learn where cold air is being wasted or air is…show more content…
Moreover, the necessity for improvements in physical modelling, in particular turbulence and combustion models. The necessity to incorporate the uncertainties associated to numerical simulations, such as operational and geometrical uncertainties. This has a major impact on the design process in order to reduce the risks associated with the simulation based decision process. Lastly ,The development of robust design methodologies taking into account the presence of uncertainties (Hirsch
