A centrifugal fan design code was developed and included in iDesignFan™. This program generates forward-curved and backward-curved bladed centrifugal fan data. With the inverse design concept used in the code, the period of designing a fan, which has given aerodynamic performance with minimal acoustic noise, is significantly shortened. A centrifugal fan design code, developed in this study and included in iDesignFan™, predicts the aerodynamic performance by using mean-line analysis and various loss models. In the period of design a lift force distribution between pressure side and suction side of blade is calculated. And then it is used to calculate steady loading noise from the impeller.
