Centrifugal fans are machines widely used in many industry sectors. Due to its importance and the fact that the use of electric energy is a concern nowadays, the search for better performance in these machines is necessary. The objective is evaluate the influence of the volute type, normal and with indentation, on centrifugal fans performance through numerical simulation using CFD techniques. The comparative study between these two types of volutes is still scarce. For each type of volute, the mass flow was varied, and thus the difference pressure and yeld curves were set up. Pressure and velocity distributions were also analyzed. The results indicated a superiority of the normal volute.
