Abstract
This work presents a preliminary project guideline of an axial fan flow using a programming platform and Computational Fluid Dynamics (CFD) to get a 3D CAD model with the main geometric and aerodynamics parameters evaluated. The linear grid and lift wing theories, the radial equilibrium and the free vortex conditions were applied in this work. The guideline turned out to be very efficient, because the axial fan sizing involves a reasonable number of variables that should be admitted, calculated and after revalidate. The initially obtained results showed to be promising. However, there was a difference in the final static pressure calculated and the one pre-established in the beginning of the project. Such fact is due to the assumption of some design variables, the choice of solidity ratio and the number of calculated blades. Such difference could be minimized through the use of optimization algorithms, however this tool was not in the scope of this work. It’s concluded that, even with this difference, the use of the proposed guideline is fundamental to obtain the first data to implement a more robust project of an axial fan.
