A Computerized System, the FANDAS Code, for Design, Flow, Performance and Noise Predicitions of Industrial Axial FAN

Chan Lee, Hyun Gwon Kil

Abstract

FANDAS (FAN Design and Analysis System) code is developed for the design, the performance and the noise predictions of industrial axial fan. In the FANDAS code, the 3-D geometrical designs for impeller blades and casing of fan are made through blade angle distribution, camber line determination and blade airfoil thickness distribution processes along blade span height, and their results are shown in GUI( Graphic User Interface ) window. Based on the design fan geometry, the FANDAS code automatically predicts the flow field inside fan and the overall performance map of fan by using flow deviation and pressure loss models. The noise level and spectrum of designed fan are also evaluated by the FANDAS code which contains noise analysis models for discrete frequency and broadband noise components of axial fan. All the performance and the noise prediction results are displayed on GUI windows. The simulation technique of the FANDAS code is coupled with the CFX code and applied to an actual air-conditioning fan design practice for optimizing design variables to maximize efficiency and minimize overall noise level of fan. The optimal fan design obtained from the FANDAS simulation results shows about 10% efficiency improvement and 11dB noise reduction compared with the commercial market product of a reference model, and its simulation results are well-agreed with the measurement within a few percent relative error.
