Using currently available CFD programs, the research is carried out in an efficient manner. At the inlet, results were obtained using typical boundary conditions, with fluid conditions at the outlet. The results showed a higher pressure of 381.62 Pa and a maximum velocity of 37.5 m/s at the outlet for these conditions. These results can also be used to compare the performance of a nine-blade axial fan with a nineand twelve-blade axial fan.

It has been observed that fluctuations in mass flow due to higher rotational speed (rpm) lead to an uneven distribution of the outlet speed of the flow line located in the ventilation hole of the stator, leading to a lower noise level. The mass flow rate is directly proportional to the performance, and pressure drop of the axial fan. The present work is carried out by considering a range of angles of (0º to 6º) for its rotor blade using trial and error in the CFD technique, we observe the axial fan handles the good volume of air at relatively low pressure and delivers good efficiency in the output airflow. Consequently, the axial fan is designed to operate on high static pressure. This manuscript consists of the computation of the aerodynamic performances of symmetrical blade profiles of a fully axial fan by Computational Fluid Dynamics (CFD) methods, developing a methodology for the design of axial fans, and analysis of the designed fan with CFD methods.
