This final project report discuss about experimental testing on axial fan design and analysis method using blade element momentum theory. This design and analysis method will be use to design and to analyze an axial fan for academic purpose. Parameters to design the axial fan are obtained through some limitation that arise when designing an axial fan system. After designing an axial fan geometry using Microsoft Excel software, 3D model will be made using CATIA software, then some real model will be manufactured using 3D Printing. Some finished real model will be tested to measure the aerodynamics parameter henceforward compared with the analytical calculation. The results are the experimental power available measured at 37 – 44 % compared to the analytical calculation, while the experimental power required measured with 12 – 34 W difference to the analytical calculation. Some things that influence the difference are aerodynamic coefficient estimation at low Reynolds number, model surface roughness due to 3D Printing manufacture method, axial gap between axial fan blade and the straightener, spinner shape, electric motor efficiency, and power required to operate the electrical circuit.
