Axial fans are important rotating machines in various fluid mechanical systems. Recently, the requirements of axial fans have become more stringent due to the sophisticated demands of fluid mechanical systems. If the boundary dimensions of an axial fan were changed to satisfy a set of requirements, the entire fluid mechanical system would be redesigned and would likely be costly. Accordingly, the development of axial fans that fulfill requirements without any change to their boundary dimensions has increased. However, depending on the expertise of the engineer and through the process of trial and error, adequate designs were made that met target requirements. Therefore, in this study, an optimal design was performed for an axial fan with variable blades. To shorten the design time, the analysis software FanDAS and PIDO software PIAnO were connected to automate the analysis procedure, and the optimization technique was used to perform the optimal design and analyze the design problem. Total Efficiency was selected as the objective function, and 11 constraints related to total pressure, number of rotor/stator blades, variable blades, and solidity were applied. Hub/tip ratio, rotor chord length, number of rotor blades, rotor setting angle, rotor camber angle, stator chord length, and number of stator blades were selected as design variables. In particular, in the case of setting angle and camber angle, parameters were introduced so that the value decreases from the Hub position to the Tip position. Optimization results revealed that the objective function was improved while satisfying all design constraints.
