Nowadays, improving energy efficient systems is one of the most controversial and significant global focuses. However, this trend in the field of engineering concentrates on the optimization of the existing technologies more than implementing new ones. Meanwhile, fans are one of the potent devices to be more efficient. Improvement in fan efficiency can be achieved by reducing material that is used in the fan blades. Due to this, decreasing the airfoil chord length to optimum value, leads to a decline in the amount of used materials in the blade design and manufacturing. In fan designing, Factor of safety should be considered. This factor changes by varying the chord length of the airfoil. However, this paper attempts to analyze the factor of safety in an axial fan blade with different chord lengths by use of finite element method. Due to this, axial fan blade with NACA5514 airfoil that is made by Aluminum 6061-T91 will be analyzed to find the correlation between the factor of safety and chord length in various pressure loads. The load values are determined by the experimental test.Keywords

In this paper different computational fluid dynamics (CFD) methods have been defined and modern methods are developed and compared with conventional ones. Numerical methods are used to calculate volume flow rates of turbines and axial flow fans. Validation of results with experimental data is improved significantly by using hollow blades and this will result to increased efficiency of turbines and large scale fans.Keywords
