Abstract

This study examines the inverse design problem (IDP) of determining the optimal three-dimensional shape of a centrifugal-flow fan based on a desired airflow rate. The desired volume airflow rate can be obtained by multiplying the airflow rate of an existing fan by a constant greater than unity. The geometry of the redesigned fan is generated using several design variables, which enables the shape of the fan to be constructed completely; thus, the parameter estimation technique used in inverse design problems can be used. Finally, prototypes of the original and optimized centrifugal fans are fabricated, and the fan performance is tested based on the AMCA-210-85 standard, which uses calibrated nozzles and pressure taps within a standardized test chamber, to verify the validity of this work. The experimental results demonstrate that by using the fabricated optimal fan, the airflow rate can be increased by 11. 8 % and the fan noise can be reduced by 3. 5 %; as a result, the performance of optimal fan is greatly improved.
